A first information report (FIR) is a document prepared by police organisations in many South and Southeast Asian countries, including Myanmar, India, Bangladesh and Pakistan, when they receive information about the commission of a cognisable offence, or in Singapore when the police receive information about any criminal offence.
These are serious criminal offences that pose an immediate danger to society such as murder, rape, or robbery.
[1] For a non-cognisable offence an entry in a community service register or in the station diary is made.
Anyone who knows about the commission of a cognisable offence, including police officers, can file an FIR.
As described in law: An FIR includes the date, time, place, incident details, and a description of the person(s) involved.
