I believe you must have a police report to do anything. Even if you have his info. I'm also not sure you can file a police report now because you have left the scene of the crime. Had a coworker that went on a delivery. Someone ran into his truck and took off. He drove back to the shop and then called the cops. Drove back out there and said there was nothing they could do cause he left the scene of accident just as the other guy did...
