Indian Railways — bidhannagar head ttec charging innocent passengers to fulfill his daily target

There is a ttec in bidhannagar railway station. I don't know his name. He is short height and dark. This particular ttec is the head ttec of bidhannagar as claimed by him. He is taking fines from passengers even if the passenger has a valid ticket. He says that the ticket is not valid. He is also encouraging other ticket examiners to do so. There is a lady who is their madam is also helping them. If a passengers do not pays then they threatens the passenger.
This particular ttec and his superior lady is the head of all these wrong doing.
Later from their conversation i came to understand that they are doing so to fulfill a target of 2500/- per day.
They don't serve for the complete duty hours. They work for an hour or so, fine innocent passengers and leave the place.
There are a few very helpful ticket examiner who helps the passenger.
I think railway ministry should take proper step against these wrong doers.
