Debt recovery

Dear sir! I'm not sure under which section exactly what my situation comes to criminal or civil. As I met one person who signed agreement with me on non judicial stamp on investment of 5 laks with monthly interest. After that this man failied paying interest on mentioned time by agreement and once noticed to return my investment back in August started lying and cheating on every date given by him recorded on call. Moreover this man was trying to sexually assault me or meanace that he not return money till not entertained sexually. It's been 5 months he was keeping lying every time and escaping answering calls on dates he was giving as a return day. I have all the calls and chats records where he promising to refund money and doesn't follow. I have bounced 2 cheques in month October. But he dint give new cheques because he was promising to return money after the cheque bounced at any cost. Now he is threatening me and my friend by advocate which I think he doesn't have but just trying to escape from paying his debt. Kindly give me any reasonable advice as I am foreign citizen and dint know all details of legal procedures for what he took advantage of. Thank u.
