Mumbai Traffic Police — I wanted to know the charges taken from me for bike parking in no parking area

Address:

400708

My bike picked up by towing vehicle at airoli. I was ready to pay penalty at the spit where it was parked. But police officer was not ready to talk at the point. He was just asking to come to traffice police station. I wanted to know is it a rule that penalty is paid only at station?. Also he took 100 rs more for towing charges. Is it a fair rule?
