Indian Railways — misbehave by rpf person

As i was travelling in punjab mail and boarded my train from kotkapura and had to go new delhi. There was a lot of rush in the train and i was travelling with a general ticket but besides getting excessive fare ticket one of the police persons in the train who was not wearing his name plate misbehaved and misconducted with me as well as other passengers also on the issue to get a seat.
Moreover he threatened me to throw down my luggage from the train and also said me to get down from the train as it was not possible for me to get down as the train has steamed off from the station.
Its my request the persons who r for our safety if they start behaving like this with the passengers what will we do.
