Indian Railways — Railway police mental harassment

Me and my brother were traveling from chandigarh to Delhi we were silently sitting on platform not initiating any inappropriate behavior suddenly 6 RPF cops came to us(one of them was Ms.shashi) and asked us to show our ID cards to them they were not checking everyone's ID...we asked them reason for checking only our ids out of 100s of persons sitting there one of the cop started raising his voice I showed my ID card and my brother too at the end they said oh they have same father's name they asked us too father's name kya h...like what?? What if we don't have same father's name then ?? Then they were about to leave when I asked them reason for checking ID they didn't specify...they insulted us in front of whole railway station without any reason what if I was with my cousin ?? Or my boyfriend I'm an adult ...my train was about to leave that why I didn't take any action but now I want to...later on when I file complaint on railway helpline they just said that it was for security purpose...6 people for just a boy and girl moreover police personnel out of them insulted a shopkeeper who asked her to pay for her water bottle she said Mai Incharge hu tujhe btaungi...I will travel by bus but not by railways...I don't pay taxes for this...they dragged a couple with them in front o[censored]s matter was to collect bribe from unmarried couples.
