Illegal Arrest in India: What Are Your Rights Under Article 22 and BNSS?

Introduction

Arrest is one of the most coercive powers available to the State.

The moment a person is arrested, their freedom of movement is taken away, they may be interrogated, produced before a court, remanded to custody and exposed to the machinery of criminal prosecution.

For precisely that reason, the Constitution of India does not permit arrest to operate as an uncontrolled police power.

Article 21 protects life and personal liberty, while Article 22 specifically guarantees safeguards to persons who are arrested.

Those constitutional protections are supplemented by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which came into force on 1 July 2024 and replaced the Code of Criminal Procedure, 1973.

The legal position has become even more significant in 2026.

On 21 September 2026, the Supreme Court in Jaskaran Jeet Singh Deol v. State of Punjab, 2026 INSC 1022, held that failure to comply with the constitutional safeguards under Article 22 can render an arrest illegal and unconstitutional. The Court also laid down new safeguards governing re-arrest after an earlier arrest has been invalidated.

The Court emphasised that the right to be informed of the grounds of arrest is not a minor procedural technicality.

It is a fundamental constitutional protection.

This article explains:

when police may arrest without a warrant;
when arrest is actually necessary;
the right to receive written grounds of arrest;
the right to inform family or friends;
the right to a lawyer;
the 24-hour rule;
rights of women;
rules on handcuffing;
the difference between arrest and a notice of appearance;
what makes an arrest illegal;
remedies against unlawful arrest;
compensation;
and the Supreme Court’s new 2026 rules on re-arrest.

What Is an Arrest?

Indian criminal procedure does not treat arrest merely as a formal declaration that a person has been arrested.

An arrest occurs when a person’s liberty is lawfully restrained by authority so that they are no longer free to leave.

The police may arrest a person:

pursuant to a warrant issued by a court; or
without a warrant where the BNSS or another law permits it.

But the existence of a criminal allegation does not automatically mean that arrest is necessary.

This distinction is fundamental.

A person may be accused of an offence and still be investigated without being arrested.

Article 21: Personal Liberty Is the Starting Point

Article 21 of the Constitution provides that no person shall be deprived of life or personal liberty except according to procedure established by law.

Modern constitutional jurisprudence requires that such procedure be fair, just and reasonable.

An unlawful arrest therefore raises more than a technical violation of criminal procedure.

It can amount to an infringement of a fundamental right.

The Supreme Court has previously recognised that wrongful arrest can violate Article 21 and may justify compensation in appropriate cases. (api.sci.gov.in)

Article 22: Constitutional Rights of an Arrested Person

Article 22 creates specific safeguards.

Broadly, an arrested person has the constitutional right:

to be informed, as soon as may be, of the grounds of arrest;
not to be denied the right to consult and be defended by a legal practitioner of choice; and
to be produced before the nearest Magistrate within 24 hours of arrest, excluding the time necessary for the journey.

A person cannot ordinarily be detained beyond that period without the authority of a Magistrate.

These safeguards are foundational protections against arbitrary detention.

Right to Know the Grounds of Arrest

One of the most important rights is the right to know why you are being arrested.

Section 47 of the BNSS provides that every police officer or other person making an arrest without warrant must communicate the full particulars of the offence or other grounds for arrest.

Where the offence is bailable, the arrested person must also be informed that they are entitled to bail and may arrange sureties. (indiacode.nic.in)

But recent Supreme Court jurisprudence has gone further.

Must the Grounds of Arrest Be Given in Writing?

Yes.

The modern Supreme Court position is that grounds of arrest must ordinarily be furnished in writing.

In Mihir Rajesh Shah v. State of Maharashtra, decided on 6 November 2025, the Supreme Court held that the requirement to inform an arrested person of the grounds of arrest applies across offences, including offences under the BNS.

The Court held that:

the grounds must be communicated in writing;
the communication should be in a language the arrested person understands;
the requirement applies across offences and statutes; and
failure to comply can render the arrest and subsequent remand illegal.

The judgment builds upon earlier decisions including:

Pankaj Bansal v. Union of India;
Prabir Purkayastha v. State (NCT of Delhi); and
Vihaan Kumar v. State of Haryana.

Can Police Give the Grounds Later?

The Supreme Court in Mihir Rajesh Shah recognised that exceptional circumstances may make immediate written communication impractical.

For example, where an offence against body or property is committed in flagrante delicto and immediate arrest is required, the arresting officer may initially communicate the grounds orally.

However, the written grounds must subsequently be supplied within a reasonable time and, in any event, at least two hours before the person is produced before the Magistrate for remand.

This two-hour period is intended to provide meaningful time for the accused and counsel to:

understand the allegations;
examine the basis of arrest;
prepare objections to remand; and
seek bail where appropriate.

Failure to comply can invalidate the arrest.

Why Are Written Grounds So Important?

The grounds of arrest serve several purposes.

Without knowing the precise reasons for arrest, a person cannot effectively:

challenge the legality of the arrest;
apply for bail;
oppose police custody;
obtain legal advice;
identify factual inaccuracies;
or prepare a defence.

The Supreme Court has therefore repeatedly emphasised that communicating the grounds is not an empty ritual.

It enables meaningful exercise of constitutional rights.

Arrest and Grounds of Arrest Are Not the Same as an FIR

Police sometimes take the position that an arrested person already knows why they were arrested because:

the FIR has been registered;
the allegations are known;
the person was previously questioned; or
the case is widely reported.

That does not automatically satisfy Article 22.

The constitutional obligation is to inform the arrested person of the grounds for the particular arrest.

General awareness of allegations is not necessarily equivalent to being supplied the legal and factual grounds relied upon by the arresting authority.

When Can Police Arrest Without a Warrant?

Section 35 BNSS contains the principal framework for arrest without warrant.

For cognizable offences punishable with imprisonment up to seven years, arrest is not automatic merely because police believe the person committed the offence.

The officer must have reason to believe that the person committed the offence and must additionally be satisfied that arrest is necessary for one or more specified reasons, including:

preventing further offences;
proper investigation;
preventing disappearance or tampering with evidence;
preventing threats, inducements or promises to witnesses; or
ensuring the person’s presence before the court.

The police officer must record reasons for arrest in writing.

Where arrest is not required, the officer must also record reasons for not making the arrest.

This embodies an important principle:

The power to arrest is not the same thing as the need to arrest.

Arrest Should Not Be Routine

The Supreme Court has repeatedly warned against mechanical arrests.

In Joginder Kumar v. State of U.P., the Court stressed that an arrest cannot be justified merely because the police have the legal power to arrest.

In Arnesh Kumar v. State of Bihar, the Supreme Court similarly emphasised that arrest should not become an automatic response in offences carrying punishment up to seven years.

These principles remain highly relevant under Section 35 BNSS.

Police must ask whether custody is actually necessary for investigation.

Notice of Appearance Instead of Arrest

Where arrest is not required, the BNSS provides for a notice directing the person to appear before the police.

This is an important safeguard.

If a person complies with such a notice and continues to cooperate, arrest should not ordinarily follow unless the police officer records reasons demonstrating why arrest has subsequently become necessary.

The notice mechanism is designed to reduce unnecessary arrests while allowing investigation to continue.

Right to Inform Family or Friends

Section 48 BNSS imposes a specific duty upon the arresting authority.

The police officer or other person making an arrest must promptly inform:

a relative;
friend; or
another person nominated by the arrested person

about the arrest and the place where the arrested person is being held.

The information must also be communicated to the designated police officer in the district.

The arrested person must also be informed of this right.

This safeguard is intended to prevent people from effectively disappearing into police custody without their family knowing where they are.

Duty of the Magistrate

The Magistrate before whom the arrested person is produced is not expected to act as a rubber stamp.

The Magistrate must examine whether statutory and constitutional safeguards have been followed.

This includes questions such as:

Were grounds of arrest supplied?
Were they supplied in writing?
Was the relative or nominated person informed?
Was the accused produced within 24 hours?
Is police custody genuinely necessary?
Was the arrest itself legally justified?

A remand order should not automatically cure an unconstitutional arrest.

The 24-Hour Rule

Article 22(2) requires an arrested person to be produced before the nearest Magistrate within 24 hours, excluding necessary travel time.

Police cannot simply keep a person in custody for several days before seeking judicial authority.

Detention beyond the constitutionally permitted period requires a Magistrate’s authorisation.

Violation of this requirement can render the detention unconstitutional.

The Supreme Court’s 2026 ruling has strongly reinforced the significance of Article 22(2).

What If Police Produce the Person After 24 Hours?

Where the constitutional time limit is breached, the detention becomes vulnerable to challenge.

The arrested person may seek immediate release and other remedies.

The seriousness of the accusation does not automatically excuse failure to comply with Article 22.

The Supreme Court has emphasised that constitutional protections are not offence-specific unless the Constitution or a valid special-law framework provides otherwise.

Right to Consult a Lawyer

Article 22(1) guarantees an arrested person the right to consult and be defended by a lawyer of choice.

The BNSS also recognises access to an advocate during interrogation, although not necessarily throughout every moment of questioning in the same manner as unrestricted participation by counsel.

The presence and assistance of legal counsel can be particularly important at the remand stage.

A lawyer can:

challenge arrest;
oppose police custody;
seek bail;
raise allegations of mistreatment;
request medical examination;
and ensure that procedural protections are observed.

Right Against Self-Incrimination

Article 20(3) provides that no person accused of an offence shall be compelled to be a witness against themselves.

This means police cannot lawfully compel an accused to make a testimonial confession.

Confessions to police are themselves subject to strict evidentiary rules.

However, Article 20(3) does not mean a person can lawfully obstruct every investigative step.

Questions involving fingerprints, biological samples, handwriting, passwords, electronic devices and other forms of evidence are governed by more specific constitutional and statutory principles.

Right to Medical Examination and Protection From Custodial Abuse

An arrested person has a right to humane treatment.

Police custody is not punishment.

The Constitution does not permit torture or degrading treatment merely because a person is accused of an offence.

The landmark decision in D.K. Basu v. State of West Bengal laid down safeguards aimed at preventing custodial torture and disappearance.

These include requirements concerning arrest records, identification of officers, information to relatives and medical safeguards.

Those principles continue to form part of the constitutional framework governing arrest.

Can Police Handcuff an Arrested Person?

The BNSS expressly addresses handcuffing in specified circumstances.

Section 43 permits handcuffs in certain categories of cases, including situations involving repeat offenders and specified serious offences.

However, the existence of statutory power does not mean handcuffing should become routine humiliation.

The use of restraints must still comply with constitutional requirements governing dignity, necessity and proportionality.

An ordinary accused should not be publicly paraded in restraints merely to create spectacle.

Special Protection for Women

The BNSS contains important safeguards concerning arrest of women.

As a general rule, a woman should not be arrested after sunset and before sunrise except in exceptional circumstances and subject to the prescribed judicial procedure.

Arrest involving physical contact should ordinarily be carried out by a woman police officer, subject to the statutory framework.

The underlying constitutional principle is protection of dignity and safety during arrest.

Can a Woman Be Called to a Police Station for Questioning?

Certain categories of persons, including women and specified vulnerable individuals, receive procedural protections regarding where they can be required to attend during investigation.

Depending upon the applicable provision and facts, questioning may need to occur at the person’s residence rather than requiring attendance at the police station.

This is distinct from a lawful arrest.

Arrest of Elderly or Infirm Persons

The law increasingly requires greater caution where arrest concerns:

elderly persons;
infirm individuals;
persons with disabilities; or
individuals whose custodial interrogation is not genuinely necessary.

The necessity of arrest should always be assessed rather than assumed.

What Makes an Arrest Illegal?

An arrest may be illegal for several reasons.

Examples include:

No lawful authority

The arresting officer had no statutory basis to arrest.

Failure to satisfy Section 35

Police arrested mechanically despite the absence of necessity.

Failure to communicate grounds of arrest

The person was not told why they were arrested.

Failure to provide written grounds

Where the constitutional requirement applies and the written grounds are not furnished in accordance with Supreme Court directions.

Grounds supplied too late

The written grounds were not supplied within the required timeframe before remand.

Production beyond 24 hours

The person was detained beyond the constitutional period without judicial authority.

Procedural violations

Mandatory arrest procedures were ignored.

Arrest despite compliance with notice

Police arrested a cooperating person without recording a valid basis explaining why arrest became necessary.

Each case depends on its own facts.

Supreme Court’s September 2026 Judgment: Jaskaran Jeet Singh Deol v. State of Punjab

The Supreme Court’s decision of 21 September 2026 represents one of the most important recent developments in Indian arrest law.

The case arose from an arrest in a criminal case involving allegations under the POCSO Act and BNS.

The arrested person was ultimately released after the arrest was found defective because of violations of Article 22 safeguards.

The question then became:

Can the police simply arrest him again?

The Supreme Court answered that question by imposing substantial safeguards.

Illegal Release Is Not “Bail”

The Court made an important conceptual distinction.

Where a person is released because the arrest itself violated Article 22, that release should not be treated in the same way as ordinary bail.

The person is being released because the initial deprivation of liberty was illegal and unconstitutional.

The arrest itself is set aside.

This distinction matters because the State cannot simply proceed as though a perfectly lawful arrest had merely ended with bail.

Can Police Re-Arrest After an Illegal Arrest?

Possibly—but not automatically.

The Supreme Court held that the power to re-arrest should not simply be left to the discretion of the same authority that violated the person’s constitutional rights.

Where the investigating agency considers fresh custody necessary, it must follow a judicially supervised process.

New Re-Arrest Procedure

Following Jaskaran Jeet Singh Deol, where an earlier arrest is declared illegal for violation of Article 22 safeguards, the investigating agency must take additional steps before re-arrest.

Broadly, the agency must:

first furnish the grounds of arrest;
approach the jurisdictional Magistrate;
explain why custody is still necessary;
explain the earlier constitutional non-compliance; and
obtain judicial approval.

The application must also carry appropriate supervisory endorsement.

The Magistrate must independently determine whether re-arrest is genuinely justified.

Investigation Must Be Reassigned

The Supreme Court went further.

Where re-arrest is sought following an unconstitutional arrest, the Court directed that further investigation should not simply continue under the very same officer responsible for the earlier violation.

The investigation is to be transferred to another officer, along with administrative accountability measures.

Departmental Inquiry Against the Arresting Officer

The 2026 ruling also introduces a strong accountability mechanism.

The Court held that where an officer arrests a person without furnishing the constitutionally required grounds, a departmental inquiry should be initiated against the concerned officer.

This reflects a significant shift from treating unlawful arrest merely as a defect in the criminal case.

The officer responsible may personally face administrative consequences.

Can a Victim of Illegal Arrest Receive Compensation?

Yes, in appropriate cases.

Indian constitutional law recognises public-law compensation for serious violations of fundamental rights.

Earlier Supreme Court authorities have awarded compensation in cases involving:

wrongful arrest;
illegal detention;
custodial violence;
and other serious infringements of Article 21.

The Supreme Court’s September 2026 ruling reaffirmed that High Courts may award compensation in cases involving violation of Article 22, without preventing the victim from pursuing separate civil remedies where available.

Compensation is therefore not merely theoretical.

Writ of Habeas Corpus

One of the most powerful remedies against unlawful detention is a petition for habeas corpus.

The expression broadly means:

“produce the body.”

A High Court under Article 226, and the Supreme Court under Article 32 in appropriate circumstances, can examine whether a person’s detention has lawful authority.

If the detention is unlawful, the court may order release.

Habeas corpus is especially important where:

the whereabouts of a detainee are unclear;
police deny custody;
procedural protections have been disregarded;
or detention continues without legal authority.

Bail and Challenge to Arrest Are Different

A person can challenge the legality of arrest even where bail is also available.

The two questions are different.

Bail asks:

Should this person remain in custody pending proceedings?

Challenge to arrest asks:

Was the person’s liberty lawfully taken away in the first place?

A person should not be forced to choose conceptually between these remedies.

An arrest may be illegal even where the prosecution case itself continues.

Does an Illegal Arrest End the Criminal Case?

No.

This is another important distinction.

An unconstitutional arrest does not automatically mean:

the FIR disappears;
the investigation ends;
the accused is innocent;
or the criminal proceedings must necessarily be quashed.

The prosecution can continue if otherwise lawful.

The consequence concerns the legality of the deprivation of liberty.

The State must investigate while respecting constitutional procedure.

Does the Seriousness of the Offence Matter?

The seriousness of an allegation may be relevant to:

necessity of custody;
bail;
public safety;
evidence protection; and
investigation.

But seriousness does not eliminate Article 22.

The Supreme Court in 2026 rejected the idea that constitutional safeguards can be diluted simply because the accusation is serious.

Constitutional rights are most important precisely when State power is most coercive.

What Should You Do If Police Come to Arrest You?

A person facing arrest should remain calm and avoid physically obstructing police officers.

You may ask:

What offence am I being arrested for?
What are the grounds of arrest?
Please provide the grounds in writing.
What is the FIR number?
Which police station is investigating?
Are you arresting me under a warrant or without a warrant?
May I contact my lawyer?
Please inform my family or nominated person.
Where will I be taken?

Do not sign blank papers.

Do not destroy evidence.

Do not attempt to escape.

And do not physically resist a lawful arrest.

Rights are best asserted through documentation, counsel and judicial proceedings.

What Should the Family Do?

Where a family member is arrested:

identify the police station and investigating officer;
obtain the FIR details where available;
contact a lawyer promptly;
confirm where the person is being held;
note the exact time of arrest;
ask whether written grounds have been supplied;
attend the remand hearing where appropriate;
preserve call records and communications;
record any visible injuries or allegations of mistreatment; and
seek urgent judicial relief where detention appears unlawful.

The time of arrest matters significantly because of the 24-hour rule.

What Should a Magistrate Examine During Remand?

A remand proceeding should not be reduced to signing a police request.

The Magistrate should consider:

legality of arrest;
communication of grounds;
time of arrest;
compliance with Article 22;
compliance with Sections 47 and 48 BNSS;
medical condition;
necessity of police custody;
alleged mistreatment;
access to counsel;
and whether the accused was produced within the permitted period.

Judicial scrutiny is the principal institutional check on police detention.

Can Police Custody Be Granted Automatically?

No.

Police custody is a serious intrusion on liberty.

The investigating agency must justify why custodial interrogation is necessary.

Factors might include:

recovery of evidence;
confrontation with material;
identification of co-accused;
tracing proceeds of crime;
or other legitimate investigative requirements.

Merely repeating that “investigation is ongoing” should not substitute for reasons.

Remedies Against Illegal Arrest

Depending on the circumstances, an arrested person may pursue:

Immediate release

Where the arrest itself is unconstitutional.

Habeas corpus

Where detention is without lawful authority.

Bail

Where continued detention is not justified.

Challenge to remand

Before the Magistrate or higher court.

Writ petition

Under Article 226 or, in appropriate cases, Article 32.

Compensation

For established fundamental-rights violations.

Departmental complaint

Against officers responsible for misconduct.

Civil damages

Where the factual and legal basis for private-law damages exists.

Criminal proceedings

In extreme circumstances involving unlawful confinement, violence or other offences, separate criminal consequences may arise.

D.K. Basu Safeguards Still Matter

The Supreme Court’s landmark decision in D.K. Basu v. State of West Bengal remains central to Indian arrest law.

Its safeguards sought to reduce custodial abuse through requirements such as:

identifiable arresting officers;
arrest memo;
witness to arrest;
notification of relatives;
diary entries;
medical examination;
and access to legal assistance.

Modern BNSS safeguards should be understood as operating alongside the constitutional principles developed through these cases.

Illegal Arrest vs Wrongful Prosecution

These concepts should not be confused.

A person can be lawfully arrested but later acquitted.

That does not automatically mean the arrest was illegal.

Conversely, an arrest may be unconstitutional even where investigators later obtain evidence supporting prosecution.

The legality of arrest is assessed according to the facts and law existing at the time State power was exercised.

Frequently Asked Questions

Can police arrest me without an FIR?

In some circumstances, yes.

The legality depends on the statutory power invoked and facts of the case.

However, arrest without a lawful basis can be challenged.

Must police show an arrest warrant?

Not where the BNSS authorises arrest without warrant.

But the officer must still have lawful grounds and comply with arrest safeguards.

Must police tell me why I am being arrested?

Yes.

Article 22(1) and Section 47 BNSS require communication of the grounds of arrest. Current Supreme Court law requires written grounds in accordance with the principles laid down in Mihir Rajesh Shah.

Must the grounds be in writing?

Ordinarily, yes.

In exceptional urgent circumstances they may initially be communicated orally, but written grounds must be supplied within the timeline laid down by the Supreme Court.

What happens if written grounds are not provided?

The arrest and subsequent remand can be rendered illegal, entitling the person to release.

Can police arrest me again immediately after an illegal arrest?

Not simply on their own discretion.

Following the Supreme Court’s September 2026 ruling, fresh custody after an unconstitutional arrest requires additional procedural safeguards and judicial approval.

Can I receive compensation?

Yes, in appropriate cases involving unconstitutional arrest or detention.

Can police keep me at the station for more than 24 hours?

Not without the authority of a Magistrate, excluding the permitted travel-time calculation under Article 22(2).

Can police prevent me from contacting a lawyer?

An arrested person has a constitutional right to consult and be defended by a lawyer.

Must police tell my family?

Section 48 BNSS requires information about arrest and place of detention to be given to a relative, friend or another person nominated by the arrested individual.

Does illegal arrest make the accused innocent?

No.

It invalidates the unlawful deprivation of liberty; the criminal investigation may otherwise continue according to law.

Practical Arrest-Rights Checklist

If you or someone you know is arrested, check the following:

Was the arrest legally authorised?

Were the grounds of arrest communicated?

Were written grounds supplied in a language the person understands?

Was the person allowed access to a lawyer?

Was a family member or nominated person informed?

Was an arrest memo prepared?

Was the person medically examined where required?

Was the arrested person produced before a Magistrate within 24 hours?

Did the Magistrate independently examine the legality of arrest?

Was police custody supported by reasons?

If several of these safeguards are missing, urgent legal review may be necessary.

Conclusion

An arrest is not merely an investigative step.

It is an exercise of State power that directly takes away personal liberty.

That is why the Constitution deliberately places safeguards around it.

Article 22 requires the arrested person to be informed of the grounds of arrest, protects access to legal counsel and requires production before a Magistrate within 24 hours.

The Bharatiya Nagarik Suraksha Sanhita builds upon those protections.

Section 35 restricts mechanical arrest in many cases.

Section 47 requires communication of the grounds of arrest.

Section 48 requires information to be given to relatives or other nominated persons.

And the broader BNSS framework regulates how arrest, custody and remand must be carried out.

The Supreme Court’s recent jurisprudence has significantly strengthened these rights.

In Mihir Rajesh Shah v. State of Maharashtra, the Court made clear that grounds of arrest must ordinarily be communicated in writing and in a language understood by the arrested person.

And on 21 September 2026, in Jaskaran Jeet Singh Deol v. State of Punjab, the Supreme Court went further.

It held that violation of Article 22 safeguards can make the arrest itself unconstitutional, required judicial scrutiny before re-arrest, directed investigation by another officer in such cases and contemplated departmental accountability against officers responsible for violating constitutional requirements.

The emerging principle is therefore clear:

Police possess the power to arrest, but that power exists within the Constitution—not above it.

The seriousness of an accusation cannot erase fundamental rights.

Nor can a subsequent remand automatically transform an unconstitutional arrest into a lawful one.

A lawful criminal-justice system must be capable of doing two things simultaneously:

investigating crime effectively and protecting individual liberty.

Article 22 and the BNSS provide the procedural architecture for achieving that balance.

For citizens, the most important practical rights to remember are simple:

Know why you are being arrested. Ask for the grounds in writing. Contact a lawyer. Ensure your family knows where you are. Remember the 24-hour rule. And challenge detention promptly where constitutional safeguards are violated.

These are not privileges given by the police.

They are rights guaranteed by law.
