Hello,
Thank you for posting your query.
You may register an FIR against the culprit under section 354 or 354A IPC. The police will take appropriate action against the person.
In case the SHO refuses to register the FIR, you may send the FIR to SP Office or alternative file a complaint before a Magistrate.
You may also complaint to the next higher authority in written about the behavior of the HM in case you don't want to register an FIR.
Thanks & Regards,
Nishant
