Indian Railways — Local people interfere in the train

We have bearded to Ala Hazrat Express (14311) with our reserved seats (seat number 73 and 79). One person boraded from Hapur (without ticket) and start fighting for reserved seat. He beaten me and the CRPF police is seeing everything and didn't take any action against him. They have setting with TC and CRPF police. I am worried about the Indian railway reservation system. I think, i may not suffer in future with Indian railway. I am working in IIT Delhi and worried about local gunda girdi and food mafiay. You may not take action on these ssues, but as Indian I need to report this issue to Indian railway.
Thanking you
Yours Sincerely
Amit
