He exited the vehicle and sought refuge inside of the school, while the driver of the BMW tried to hit the group on the sidewalk with his vehicle.
In doing so, he collided with a 2007 Chrysler PT Cruiser that was double parked, which then his at least one pedestrian.
The driver of the Chrysler remained at the scene and was among the people injured during the incident.
The operator of the BMW got out of the car and fled the scene.
"He turns his car, comes this way, I thought he was going to stop because he seen my car is double parked," said a woman who was in the PT Cruiser. "He did not. He just rammed the car, trying to hit the kids. Then he backs up, goes over there, trying to get away but I think something happened with his car. He got out. They were fighting...He's standing here and he's saying, 'It's me, it's me, I get it, I get it,' but no one paid any attention to him. So he ran off that way, and that's the last I saw of him."
Arriving officers found the 17-year-old male with a laceration to his torso and an additional seven to eight individuals with minor injuries.
