An investigation is underway after a Los Angeles police officer’s personal rifle accidentally fired a round in a parking garage earlier this week, officials announced. The May 9 incident occurred in the lower-level parking structure of the Compton Courthouse, located at 200 West Compton Boulevard, according to an LAPD news release. The officer, who has not been identified, was reportedly standing outside his patrol vehicle and was “manipulating his personally owned patrol rifle, when a Non-Tactical Unintentional Discharge occurred,” police said. Surrounded by concrete, the bullet ricocheted off the ceiling and struck the roof of the officer’s unoccupied patrol vehicle.
