A domestic dispute turned into a violent rampage in a California parking lot.
Good Samaritans rushed to help a woman being attacked by her boyfriend, but the witnesses soon became targets themselves.
At one point, the driver crashed into the group, knocking a woman to the ground.
As the group hurried to help the woman he nearly ran over, the driver took off.
The group tracked the driver down and called the police. The camera was still rolling as the driver was taken into custody.
