Maharashtra Traffic Police — Wrong challan issued

We have been residing in the area since 50 years, and have been parking on the roads with ease and now we are getting challans of rs.1500 every alternate day because the officer thinks thinks its a no parking zone. However, there isnt any NO parking board or zone but on questioning the officer - Aslam Khan, he misbehaved and now is targeting our cars anywhere it is parked by issuing an echallan! He states that they are the cops and have the authority to fine whoever they want! Please help!
