explain all to police officer all what really happened. eventhough the second party did not showed up, the police officer will still make a report for u after checking your car and make assessment whose really fault is. If police officer found that it is second party's fault, they will give u a police report, which indicate the insurance company of second party, u need to go to that insurance company, they will advise u where to bring the car for reparation. It is better that u have a proof like photo....
