Three die in US pizzeria shooting
Three people have been killed and seven injured after a gunman fired into a group of people outside a pizza restaurant.
Police said they were still seeking the gunman.
Investigators were trying to determine whether the shooting was gang related, said Los Angeles County sheriff's Deputy Keith Ho.
The shooting happened during a fundraiser held by a motorcycle group called the Old School Riders. People who gathered in the car park of Falcone's Pizza were fired upon by a gunman who then jumped into a dark-coloured vehicle, Mr Ho said.
"The suspect started firing into the crowd without provocation," the deputy said.
Three men, two of them brothers, died at the scene. Seven other people were taken to hospital.
Pico Rivera is about 15 miles east of downtown Los Angeles.
