A Homeland Security agent is suing the San Diego Police Department, accusing an off duty officer of using excessive force in a Costco parking lot.
Security footage shows officer Jonathan Ferraro, who was in plain clothes, slamming Chu Ding, also in plain clothes, to the ground. Ding became unconscious.
NBC 7 reports the confrontation stemmed from an an argument over a parking space. Ding tapped on Ferraro's window to let him know he was in the way as Ding was trying to leave, causing Ferraro to jump out of the truck to slam Ding to the ground.
Ding's attorney is calling for an internal affairs investigation and stricter disciplinary measures against the officer involved.
