I was duped of XX amount by an individual with false identity n false reason, I filled the police complaint n after verifying the facts he was arrested, he agreed to pay me back n produced a DD in court , on this condition he was bailed, but the DD is with him and now he is not giving it neither answering police. since the case is Police vs accused, I event being the complainant was never called for any proceeding. I was manipulated to take the loan of XX amount n transfer to this person's account. With all this delay I am suffering as he is bailed n I haven't received the amount. Please suggest me how should I go ahead with this.
