Arrest to prevent commission of cognizable offences.
What this section does
A police officer who knows of a design to commit a cognizable offence may arrest the person so designing without a Magistrate's order or warrant, if the officer believes the commission of the offence cannot otherwise be prevented. A person so arrested shall not be detained for more than twenty-four hours from the time of arrest unless further detention is required or authorised under the Sanhita or any other law in force.

Why this matters
BNSS Section 170 forms part of Bharatiya Nagarik Suraksha Sanhita which replaced the Code of Criminal Procedure 1973 on 1 July 2024. Any new filing, FIR, charge sheet, or bail application made on or after that date should cite the new section number. References to the old act in legacy documents remain valid for matters that arose before the changeover.
