Two California police officers responding to a report of a man with a knife accidentally shot each other, authorities say.
Both officers were released from the hospital after being treated for minor injuries sustained during the confrontation in Huntington Beach on Thursday.
The suspect, who was also shot, remained hospitalised with non-life-threatening injuries.
A preliminary investigation found the officers "were injured by friendly fire", according to a statement by the Orange County Sheriff's Department.
They were called to a residential neighbourhood in the coastal city south of Los Angeles on a report of a man with a knife slashing tires.
