Car damaged by 6 men and damaged door frame, what to do?

So the other night my car was was caught in the middle of a huge fight. Two guys were being attacked by 6 very big guys and were fighting in front of my car and this morning I go to open my door and I notice their is a chip on the frame of the car, it seems someone punched my car and it chipped off a piece. Because their were so many guys surrounding my car I can't pinpoint the one person who did it? What are my options
