First information report


A first information report is a document prepared by police organisations in South Asian 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. It generally stems from a complaint lodged with the police by the victim of a cognisable offence or by someone on his or her behalf, but anyone can make such a report either orally or in writing to the police, so it is necessary to know about cognizable offences. These are serious criminal offences that poses an immediate danger to society such as murder, rape, or robbery.
For a non-cognisable offence an entry in a community service register or in the station diary is made.
Each FIR is important as it sets the process of criminal justice in motion. It is only after the FIR is registered in the police station that the police take up investigation of most types of cases. 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 involved.
