CHAPTER XII: PREVENTIVE ACTION OF THE POLICE
This short chapter outlines the basic duty and powers of the police to stop crimes from happening.
Section 168: Police to prevent cognizable offences
- Simple English: Every police officer has a legal duty to step in and do everything they can to prevent a cognizable offence (a serious crime) from being committed.
- Real-World Example: A police officer on patrol sees two people starting a violent fight that could lead to “grievous hurt” (a cognizable offence). The officer’s duty under this section is to immediately intervene and stop the fight.
Section 169: Information of design to commit cognizable offences
- Simple English: If a police officer receives any information about a plan (“design”) to commit a serious crime, they must immediately communicate this information to their superior officer and to any other officer who has the authority to prevent or take action on that crime.
- Real-World Example: A junior constable gets a tip that a dacoity is being planned for that night. He must immediately inform his Station House Officer (SHO). The SHO then informs the Superintendent of Police (SP) and the officer in charge of the nearby police station where the dacoity might happen.
Section 170: Arrest to prevent commission of cognizable offences
- Sub-section (1):
- Simple English: A police officer who knows about a plan to commit a serious crime can arrest the person planning it, without a warrant, if the officer believes that arresting them is the only way to prevent the crime from happening.
- Real-World Example: Police get a credible tip that a man is on his way to his ex-wife’s house with a gun to kill her. The officers find him in his car, and he has the gun. They can arrest him immediately under this section to prevent the planned murder, even though he hasn’t yet committed it.
- Sub-section (2):
- Simple English: A person arrested preventively under this section cannot be held in custody for more than 24 hours. After 24 hours, the police must either release them or (if they have enough evidence of a crime) get an order from a Magistrate to detain them longer.
- Real-World Example: The police arrest the man with the gun at 6 PM on Tuesday. They must bring him before a Magistrate by 6 PM on Wednesday. They cannot just hold him for 3 days to “teach him a lesson.”
Section 171: Prevention of injury to public property
- Simple English: A police officer has the authority to step in on their own (without orders) to stop anyone they see trying to damage or deface public property. This includes:
- Movable property (like a police van or a public bus).
- Immovable property (like a statue, monument, or government building).
- Any public landmark, buoy (a navigation marker in water), or other mark used for navigation.
- Real-World Example: A police officer on patrol sees a person about to spray-paint graffiti on a public statue or break the windows of a public library. The officer has the immediate authority under this section to intervene and physically stop the person from causing the damage.
Section 172: Persons bound to conform to lawful directions of police
- Sub-section (1):
- Simple English: All members of the public must obey the lawful and reasonable directions given by a police officer who is performing their preventive duties (as described in this chapter, like preventing a crime or protecting property).
- Real-World Example: Police are securing a public park (under Section 171) because of a bomb threat. They create a perimeter and order all bystanders to “move back behind this line.” You are legally required to obey that direction.
- Sub-section (2):
- Simple English: If a person resists, refuses, ignores, or disregards a lawful order given under sub-section (1), the police officer can detain or physically remove that person.
- After detaining them, the officer can either:
- Take them before a Magistrate for legal action.
- In “petty cases” (minor issues), the officer can just release the person as soon as possible, but no later than 24 hours.
- Real-World Example: You refuse to move back from the police line in the park. The officer can lawfully detain you, move you from the area, and hold you at the station. Since this is a petty offense (just disobeying an order), the officer can release you a few hours later once the danger is gone, without needing to take you to court.
