It is well settled that a first information report is not an encyclopaedia, which must disclose all facts and details relating to the offence reported. An informant may lodge a report about the commission of an offence though he may not know the name of the victim or his assailant. He may not even know how the occurrence took place. A first informant need not necessarily be an eyewitness so as to be able to disclose in great detail all aspects of the offence committed. What is of significance is that the information given must disclose the commission of a cognizable offence and the information so lodged must provide a basis for the police officer to suspect the commission of a cognizable offence.
At this stage it is enough if the police officer on the basis of the information given suspects the commission of a cognizable offence, and not that he must be convinced or satisfied that a cognizable offence has been committed. If he has reasons to suspect, on the basis of information received, that a cognizable offence may have been committed, he is bound to record the information and conduct an investigation.
At this stage it is also not necessary for him to satisfy himself about the truthfulness of the information. It is only after a complete investigation that he may be able to report on the truthfulness or otherwise of the information. Similarly, even if the information does not furnish all the details he must find out those details in the course of investigation and collect all the necessary evidence. The information given disclosing the commission of a cognizable offence only sets in motion the investigative machinery, with a view to collect all necessary evidence, and thereafter to take action in accordance with law. The true test is whether the information furnished provides a reason to suspect the commission of an offence, which the police officer concerned is empowered under Section 156 of the Code to investigate.
If it does, he has no option but to record the information and proceed to investigate the case either himself or depute any other competent officer to conduct the investigation. The question as to whether the report is true, whether it discloses full details regarding the manner of occurrence, whether the accused is named, and whether there is sufficient evidence to support the allegations are all matters which are alien to the consideration of the question whether the report discloses the commission of a cognizable offence. Even if the information does not give full details regarding these matters, the investigating officer is not absolved of his duty to investigate the case and discover the true facts, if he can.
