An Oklahoma City police officer injured trying to break up a bar fight is now suing.
Officer Chad Peery was paralyzed in the attack at Dan O'Brien's. Three men are charged with assaulting him.
In the lawsuit, Peery claims Dan O'Brien's served the men too much alcohol. Then when they got rowdy, the bar asked Peery to escort them out because they didn't have security.
Peery was off duty at the time of the attack.
