Complaint [Section 2(d)]
“Complaint” means any allegation made orally or in writing to a Magistrate, with a view to his taking action under this Code that some person, whether known or unknown, has committed an offence, but it does not include a police report.
However, a report made by the police officer in a case which discloses after investigation, the commission of a non-cognizable offence shall be deemed to be a complaint, and the police officer making the report as a complainant.
