Shortly before 10:30 pm a man driving a white sedan crashed into an excavator at the construction site. Construction workers in the area saw the vehicle coming and managed to escape the impact from the car but one worker fell into a trench about 20 FT down. The worker suffered some injuries from the fall and was not able to extricate himself and was transported to UCI trauma center for his injuries. The driver of the car ran from the scene but was apprehended by police just a couple blocks away. Police say there were no signs of alcohol or drugs involved, rather the driver was just scared about what just happened and fled. He is in custody of Anaheim Police and being questioned. The Anaheim Police are investigating.
