hit by car barrie

My teenage son was hit by a car on his bike today riding on the sidewalk on Bayview as the person was turning into Park Place around noon. He was really shaken up and the person did stop and ask if he was ok but then left without giving any of their information and telling him to call his mom. Another person also stopped to help, but he let them leave without getting their information either. I've reported to the police but they say that without driver information, they can't do anything. They also say it is not a fail to remain because they did stop. His bike has some damage, but I think he is ok as he said he didn't fall on his head, but I'm really upset that a driver would hit a kid and then leave without making sure that a parent knew about it. If anyone saw this today or has any information, could you DM me? Source
