Citizen — harrasment of passengers at the tilak nagar terminus, mumbai

Sir, I am a very infrequent traveller on the harbour line of the mumbai local. I have been noticing one thing always, there is a lot of checking at the LTT. I used to appreciate it and admired the policemen and policewomen working there, untill one day I saw a young person requesting the police people there to let him go as he had no money to pay them. Since then I have been observing these policemen at the station and realised that it is practically aracket to extort money from the poor workers going towards their home town. I have stood inconspicuosly and observed the modus operandi of these checkers. They usually stop a single or maybe grp of two, young person and check there luggage and then ask money on one pretext or other. The person is usually not in a position to argue as he is their to catch a train, so they pay up and catch the train.
This is a request to kindly look into the matter and take the culprits to task so that this harrassment stops
Thank You
