CYBER CRIME RELATED ISSUE, GOT CHEATED WHILE SELLING VIA OLX

Sir, I listed my phone in Olx to sell it. However, the buyer who has approached me via Olx was an international buyer. He was offering me a good price, so I sold my phone. I shipped the phone via courier to Dubai after he sent me the payment confirmation email. But it was after a day I came to know that it is a fake email. I want to file a FIR against the person. But my question is while I sent the phone via courier I didn\'t know him and I sent it as a normal user, not a seller. and I mentioned that I am sending it only for consumption purpose, not for money. Will it be a big problem for me if I go to the police?
