Third party insurance claim for victim from the car which made accident

As I'm going to my Village in my car within Village speed limits(may be I'm driving between 60-70km/hr). Suddenly the guy in TVS XL Moped tried to slow down & turn to the right side to go for the petrol bunk without any signal/indicator. Then I suddenly controlled my car by applying brake & stopped my car within two feet distance from the TVS XL bike. But the vehicle behind my car Maruti Ertiga, he's driving well over 110-120km/hr which is not acceptable in Village speed limits & he couldn't control his car & he made an accident to my car from behind. My cars back panel(Dickey door) & spare tire & spare tire rim & rear bumper & tail lights got completely damaged. Now I had filed an FIR against him at the nearest police station. I inquired about the repair costs at my car showroom they said it'll be around [deleted] INR. Now how can I recover this money from the car that made an accident to me. Even if he haven't got THIRD PARTY INSURANCE for his car??? Please guide me here..... Hoping to get right guidance to get justice...
