Three people were killed and seven others injured in a drive-by shooting outside a pizza restaurant where a motorcycle group was hosting an event, authorities in the Los Angeles area said today.
Los Angeles County sheriff's Deputy Keith Ho said ten people gathered in the car park of the restaurant in Pico Rivera were shot at from a moving vehicle on Saturday evening.
Mr Ho said three people died at the scene. Seven others were taken to hospital in stable condition.
Nobody inside the restaurant was injured.
A biker group known as the Old School Riders was hosting an event at the time.
Mr Ho said investigators are trying to determine if the shooting was gang related. No arrests have been made.
Pico Rivera is about 15 miles east of downtown Los Angeles.
