what is priya's past?

Pls tell what is priya's past and when and how Bharma abused her? I have don't watch it regularly.

Priya was getting married and the night of her engagement she went with her fiancee for a drive and the cop arrested them for being alone at night in a car and then he wouldn't let the fiancee go and their wedding was like in couple of days so this other cop tole her to go to this senior cop guy to ask for help. So priya went on the train where the cop was and it was Brahmanand and she asked for his help and he said ok and called to get the finacee released. When priya was about to thank him she fell coz the train jerked and then Brahma started touching and trying to rape her but she fought back and pulled the chain of the train and got off. She went home and told her dad and they filed a complaint against the cop but they didn't know his name. Then the next day of priya's sangeet she got arrested on the charges of prostitution and it was publicized everywhere and the next day was her wedding but the groom and his family never came. Her dad also lost his job and cheenu had to drop out of college. Priya even got a threatening call from Brahma saying she could not win against him and she should just kill herself. That's what led to the beginning of the show where she met aditya and wanted to kill herself but he saved her.
