A police officer may arrest somebody accused of an offence

The three listed purposes are recognised grounds of arrest necessity under section 41(1)(b)(ii): prevention of another offence, proper investigation and prevention of evidence destruction or tampering. They do not make every accusation a sufficient ground for arrest; the applicable statutory conditions, reasonable belief and written reasons must also be satisfied.

Current law: BNSS section 35 retains these necessity grounds. Section 35(7) additionally requires prior permission of an officer not below Deputy Superintendent of Police to arrest an infirm person or a person above sixty for an offence punishable with less than three years imprisonment.
