You would certainly be having a CCTV camera somewhere around your society gate, try getting footage of the same. If you are confident that you did not misbehaved with the policemen on duty - you can file a complaint at the DCP office , marking a copy to the commissioner, followed by filing an FIR agaist the policemen who manhandled you.
The FIR will not be lodged for sure, then you need to get the FIR lodged u/s 156(3) and pursue the matter in court.
