TEHNICALLY, I agree with Expert "TGK REDDI":
1. You can file a Police NC, requesting investigation and charge-sheet, for offences like intimidation, breach of trust etc.... against the person, supported with all relevant supporting documents /witnesses. Alongwith above MUST file written notice to Police Commissioner /SP, against the nefarious Police person, and request to take departmental action.
2. IF the Police does not take action on the NC & Notice, THEN you can file private criminal case u/s 156(3) Cr.P.C., in the local Magistrates court, seeking directions to the Police to investigate and file charge sheet. IF at all "any" permission is required, the Police dept., will do so, without any reference to the complainant /aggrived person.
