If the Police Sub-Inspector is acting illegally, without any lawful powers, threatening you to stop work or is demanding any bribe, etc., then definitely you can file a complaint against him. If a cognizable offence is disclosed then you can try filing FIR with the concerned police station. Otherwise, if it is only a non-cognizable offence, or if it is cognizable offence but the police refuses to register FIR, then you file a direct private complaint in the Magistrate court having jurisdiction.
Offences committed would depend on the details facts and may include: criminal conspiracy, criminal intimidation (threats), demanding bribe (if any), etc. Please show the full details, including the video recorded by you, to some local lawyer to decide about the offences for which such complaint can be filed, since offences mentioned by me are only tentative and would depend on the actual facts.
