Delhi Police — complaint regarding traffic police

Address:

New Delhi, Delhi

I was overcharged fine today by delhi traffic police, without any reason,
As i was in a hurry for my office and my car was at the speed of 74 (For which i was supposed to charge 400 rs fine) while they have charged me rs. 900 including that i have not a valid license whereas i was with my proper dl.
Even my dl and my car rc was in hand he challan me for my dl which was not supposed to be. Its such a bad behavior of traffic police.
I can share my challan no. If required and what are the chances that i will get justified in this issue.
