You can file an FIR if you are:
- A victim of a crime.
- A relative or friend or acquaintance of the victim.
- You have knowledge about a crime that has taken place or is about to take place.
It is not necessary that you must have all information about the crime in order to file an FIR. But it is important that you report everything you know to the police.
An FIR in itself is not a criminal case filed against someone. It is just information received by the police relating to the commission of a crime. A criminal case begins when the chargesheet is filed by the police before the Court and a Public Prosecutor is appointed by the State.
