Yes, the police can arrest you without a warrant — but only in specific situations defined by law. Under Section 35 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023 (which replaced Section 41 of the CrPC), the police can arrest without a warrant primarily when a cognizable offence (a serious crime like theft, assault, murder, or robbery) is involved. For non-cognizable offences (minor disputes, defamation), the police cannot arrest you without first obtaining a warrant from a Magistrate.
Why this matters
The power to arrest is one of the most significant powers the State has over an individual. An arrest affects your liberty, your reputation, your job, and your family. The law carefully limits this power so that police cannot simply arrest anyone at will. The Supreme Court in Arnesh Kumar v. State of Bihar (2014) warned that the power of arrest should not be used as a "tool of harassment" and laid down strict guidelines. Knowing when the police can and cannot arrest you is essential to protecting yourself from unlawful detention.
When police CAN arrest without a warrant
1. Cognizable offence committed in the officer's presence
If a person commits a cognizable offence right in front of a police officer, the officer can immediately arrest that person. No warrant, no prior complaint, no paperwork — the officer acts on what they have directly witnessed.
Example: If a police officer sees someone stealing from a shop or physically assaulting another person, they can arrest the offender on the spot.
2. Cognizable offence with more than 7 years' imprisonment
If the police receive a credible complaint or reliable information that a person has committed a cognizable offence punishable with more than 7 years' imprisonment (or life imprisonment or death), they can arrest without a warrant under Section 35(1)(a) of the BNSS.
Examples: Murder, robbery, dacoity, kidnapping, rape — all carry sentences above 7 years.
3. Cognizable offence with up to 7 years' imprisonment (with conditions)
For cognizable offences with punishment up to 7 years, the police have a more restricted power. Under Section 35(1)(b) of the BNSS, they can arrest only if they are satisfied that:
- The arrest is necessary to prevent further offences
- The arrest is needed for proper investigation
- The person may tamper with evidence or threaten witnesses
- The person's presence before the court cannot be ensured otherwise
Important: This is a critical reform. The Supreme Court in Arnesh Kumar v. State of Bihar (2014) held that for offences punishable with up to 7 years, the police must first consider whether arrest is genuinely necessary. They cannot arrest mechanically — they must record their reasons in writing.
4. Proclaimed offender or habitual offender
If a person has been proclaimed as an offender by a court or is a known habitual offender, the police can arrest without a warrant.
5. Possession of stolen property
If the police reasonably believe that a person possesses stolen property and has committed an offence relating to it, they can arrest without a warrant.
6. Obstruction of police duty or attempt to escape
If a person obstructs a police officer in the discharge of duty, or escapes or attempts to escape from lawful custody, the police can arrest without a warrant.
7. Preventive arrest
Under Section 170 of the BNSS (earlier Section 151 CrPC), the police can arrest a person without a warrant if they have reason to believe the person is about to commit a cognizable offence and the offence cannot be prevented otherwise. However, the person must be produced before a Magistrate within 24 hours and cannot be detained beyond 24 hours without Magistrate orders.
When police CANNOT arrest without a warrant
Non-cognizable offences
For non-cognizable offences (e.g., simple defamation, minor cheating, causing simple hurt), the police cannot arrest without a warrant. They must first obtain a warrant from a Magistrate.
Without recording reasons (for offences up to 7 years)
For offences punishable with up to 7 years, the police must record their reasons in writing for believing arrest is necessary. Failure to do so makes the arrest illegal. Under Section 35(3) of the BNSS, the officer must also issue a notice of appearance instead of arresting, unless the specific conditions for arrest are met.
Women — special restrictions
Under Section 43 of the BNSS, a woman cannot be arrested after sunset and before sunrise except in exceptional circumstances, and only with prior written permission of a first-class Judicial Magistrate. Additionally, only a female police officer can arrest a woman.
What to do if you are arrested without a warrant
Step 1: Stay calm and do not resist
Resisting arrest — even if you believe it is illegal — can lead to additional charges. Cooperate physically while asserting your rights verbally.
Step 2: Ask for the reason
Under Section 47 of the BNSS (earlier Section 50 CrPC), the police must tell you the specific offence for which you are being arrested. Ask clearly: "What is the charge against me?"
Step 3: Call your lawyer immediately
You have the constitutional right under Article 22(1) to consult a lawyer. If you cannot afford one, ask for free legal aid — call NALSA at 15100.
Step 4: Ensure your family is informed
Under Section 36 of the BNSS (earlier Section 41D CrPC), the police must inform a person nominated by you about your arrest.
Step 5: Demand production before a Magistrate within 24 hours
Under Article 22(2) of the Constitution, you must be produced before a Magistrate within 24 hours (excluding travel time). If the police hold you longer without doing so, the detention is illegal.
What if things go wrong
If you believe the arrest is illegal
File a habeas corpus petition in the High Court under Article 226 of the Constitution. This is the fastest remedy — High Courts treat habeas corpus petitions with urgency and can order your immediate release.
If the police did not follow mandatory procedures
If the police did not prepare an arrest memo, did not inform your family, did not produce you before a Magistrate within 24 hours, or did not tell you the reason for arrest, all of these violations can be raised before the Magistrate and the High Court.

Common myths
Myth: The police can arrest anyone, anytime, for any reason. Reality: Warrantless arrest is limited to cognizable offences and specific conditions under Section 35 BNSS. For non-cognizable offences, a warrant is required. Even for cognizable offences up to 7 years, the police must justify why arrest is necessary.
Myth: If the police arrest you, you must have done something wrong. Reality: An arrest is not a conviction. You are presumed innocent until proven guilty by a court of law. Wrongful arrests happen, and the law provides remedies.
Myth: You cannot do anything if arrested without a warrant. Reality: You have immediate rights — right to know the charge, right to a lawyer, right to inform family, right to be produced before a Magistrate within 24 hours, and the right to file a habeas corpus petition if the arrest is illegal.
Myth: The police must always arrest in a cognizable offence. Reality: Arrest is not mandatory even in cognizable cases. The Supreme Court in Arnesh Kumar (2014) held that arrest should be the exception, not the rule, especially for offences punishable with up to 7 years.

Frequently asked questions
Can the police arrest me based on a phone call complaint? For serious cognizable offences (above 7 years), the police can arrest based on credible information, which could include a phone complaint. For offences up to 7 years, they must first issue a notice requiring you to appear, and arrest only if you fail to comply or if specific conditions are met.
Can I be arrested at night? Yes, men can be arrested at any time. However, women cannot be arrested between sunset and sunrise except with written permission from a first-class Judicial Magistrate, and only by a female police officer.
What if the police arrest me for a non-cognizable offence without a warrant? The arrest is illegal. You can file a habeas corpus petition in the High Court, complain to the Superintendent of Police, or raise the illegality before the Magistrate when produced in court.
Can a private person arrest me? Yes, under Section 38 of the BNSS (earlier Section 43 CrPC), a private person can arrest someone who commits a non-bailable and cognizable offence in their presence, but must hand the person over to the police immediately.
Does the police need to show me the FIR before arresting me? No, the police do not need to show the FIR at the time of arrest. However, they must inform you of the specific offence and the grounds for arrest under Section 47 BNSS. You are entitled to a copy of the FIR if one has been registered.
