LOS ANGELES — A civilian review board on Tuesday found that two fatal shootings by Los Angeles police officers violated the department’s deadly force rules.

The Los Angeles Police Commission found fault with the shooting of a man who threw a beer bottle at a patrol car and the shooting of a woman walking along a downtown street with an 8-inch knife, according to The Los Angeles Times, (http://lat.ms/2cnavML ).

Reports explaining the commission’s reasoning were not immediately released.

On Oct. 3, 2015, officers fatally shot James John Byrd after a bottle shattered the back window of their patrol car as they sat at a stoplight. At the time, the department said the officers believed they had come under fire.

Police did not find a gun or other weapon when they searched Byrd’s body but determined he had thrown the 40-ounce beer bottle at the car.

The shooting happened amid increased tensions at the department over an online video showing someone flashing a loaded gun while filming an LAPD officer. The video later turned out to be a publicity attempt by an old hip-hop group looking to make a comeback.

A week before Byrd’s death, LAPD officers fatally shot Norma Guzman as she approached them with a knife. Police said she ignored repeated orders to drop the weapon.
