Money fraud; not returning cash transferred

Hi, I was supposed to settle down in Delhi, with an old friend of mine (I live in Coimbatore), he requested for transferring 15,500 INR in cash, after transfer, he didnt reply, took off with the cash. When i called him up, he blocks me, tried calling him up from other numbers, still he blocks every number I call from (even on WhatsApp and Facebook). I get that 15k is pea size cash. But to me its my hard earned money. He is also rude to me when i requested the money back. Im helpless an Im not able to travel (since im a journalist) or do my work properly, all my plans to settle and go forward are spoiled because of this guy. He says he owes (currently) Rs 10 lac in cash to many other people and that 15K is nothing, I have all this on record. The threatening part and at places he has told me "I want to see you suffer and loose your job" Someone help, I will loose my job because of this person. (PS: this guy lives in delhi, i live in coimbatore; so what do I do?) Thanks in Advance....
