Authorities in the Los Angeles area say three people have been killed and seven others injured in a drive-by shooting outside a pizza restaurant where a motorcycle group was hosting an event, Associated Press reported.
Los Angeles County sheriff's Deputy Keith Ho says 10 people gathered in the parking lot of the restaurant in Pico Rivera were shot at from a moving vehicle Saturday evening.
Ho says three people died at the scene. Seven others were hospitalized 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.
Ho says 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.
