Harassment at work place

Kindly please provide me the legal options available to me in the following case:- I filed the case against the person with whom i was in relationship & he outraged my modesty in the pretext of false promise of marriage. Even after his marriage (To some other person) he kept on controlling my life ,abused me ,yelled at me ,disgraced me for partying & hanging out with other guys. He also tried to blackmail by releasing some messages (That were having some details of our personal outstation trip) to one of my colleague.He kept calling me late in the night after getting drunk when his wife was not at home in the name of emotional melodrama and all. I reported this matter to my company HR and filed POSH complaint against him.ICC was formed they did the investigation but not even a slightest action have been taken against him.Confidentiality of the case was also not maintained & this entire episode tainted my public image.So i left the company as it was getting very difficult for me to work there after all this. I asked management to share the findings of the report ,they denied & said we can tell you only in person.Company management even retaliated against me and one of the witness of the case & intruded our very personal intimate life also(asking questions of sexual history and all).Neither they are declaring it a false case nor they have taken any action. I reported this case to NCW & it has forwarded the case to the police. Please suggest me the further course of actions available to seek justice.
