Can Police Arrest You to 'Prevent' a Crime? Understanding Section 170 BNSS

A recent incident in Greater Noida caught national attention when a woman was arrested after a video showed her in a heated argument with security guards over a late-night delivery. Police invoked Section 170 of the Bharatiya Nagarik Suraksha Sanhita (BNSS) to take her into custody. The stated reason was to prevent commission of a cognizable offence.

This raises an important question: can police arrest you not for something you have done, but for something they think you might do?

Section 170 BNSS is one of the most powerful yet least understood provisions in India's new criminal procedure code. It replaced the older Section 151 of the Criminal Procedure Code (CrPC) when the new laws came into effect in 2024. This section gives police the authority to arrest any person without a warrant if the officer has information that the person is about to commit a cognizable offence.

A cognizable offence is one where police can arrest without a warrant and start investigation without court permission. These include serious crimes like assault, theft, rioting, causing hurt, or public nuisance.

Suppose you are having a loud argument with your neighbour at midnight. The dispute is escalating and someone calls the police. If the officer arriving on scene believes the situation might turn violent and someone might get hurt, they can arrest either or both parties under Section 170 to prevent that potential assault from happening.

The law requires three conditions. First, the officer must have credible information or reasonable belief that you are about to commit a cognizable offence. Second, the arrest must be genuinely to prevent that crime, not as punishment for something already done. Third, the person arrested must be brought before a magistrate within 24 hours.

Here is what many people do not realise: this is not an arrest for committing a crime. You have not been charged with any offence yet. The police are holding you temporarily to prevent a law and order situation. The magistrate will then decide whether continued detention is necessary or whether you should be released, possibly with conditions like a bond to keep the peace.

This provision has legitimate uses. It helps police prevent riots during tense situations, stop gang fights before they turn deadly, or intervene when domestic disputes are clearly about to turn violent. However, it also carries serious risks of misuse.

Because the arrest happens before any crime occurs, it relies entirely on police discretion and judgment. There is no FIR, no formal complaint, no evidence of an actual offence yet. This creates room for arbitrary action based on an officer's subjective assessment or even malicious intent.

If you are arrested under Section 170 BNSS, know your rights. First, police must inform you of the grounds for arrest. Ask clearly why they believe you are about to commit an offence. Second, you must be produced before a magistrate within 24 hours. The magistrate is not bound by the police officer's assessment and can order your immediate release. Third, this arrest should not appear on your permanent record as conviction for any crime because no crime has been proven.

You have the right to legal representation immediately. Even though this is technically a preventive measure, it is still detention and you are entitled to consult an advocate.

The key safeguard is judicial oversight. The magistrate acts as a check on police power. If the magistrate finds no reasonable basis for believing you were about to commit an offence, or if the situation has cooled down, you should be released promptly. In many cases, the magistrate will release you on a personal bond with a promise to maintain peace and good behaviour.

What should you do if you find yourself in a heated public dispute? Stay calm and avoid any threatening language or gestures. If police arrive, cooperate respectfully but do not make any statements that could be interpreted as intention to harm or damage property. Remember that the officer's perception of the situation matters greatly in these cases.

If you believe you were wrongfully arrested under this provision, you can file a complaint with senior police officials or approach the magistrate for immediate relief. You may also have grounds for a legal challenge if the arrest was made in bad faith or without any reasonable basis.

This law walks a fine line between preventing crime and protecting individual liberty. Understanding it helps you navigate difficult situations without unwittingly giving police a reason to invoke these powers.
