Breach of contract by buyer

I was working in gurgaon and am a permanent resident of lucknow. Recently i got married and shifted to the US. During this transition i wanted to sell my car and a person approached me via a friend and checked the car and agreed to buy the car for Rs3.25 lac. He transfered me an advance of Rs 75000 online. He knew i was moving back to lucknow as my marriage was scheduled within 15 days. He delibrately delayed the remaining payment and wanted me to handover the car to him in gurgaon itself before leaving, which i did not coz i had not received the entire payment. I sent him a legal notice clearly stating that if he does not give the remaining payment within a week and pick up the car from me, the advance shall be forfieted and not returned. After a few days i also offered him to return half of his amount but he wanted the car and not the money. Now when i have shifted to the US he has filed an FIR against me in gurgaon. My parents who are residing in lucknow are receiving calls from police. Plz help
