Two people were listed in critical condition after the shooting reported around 7:30 p.m. and the suspects are still on the loose. At least two vehicles with heavy damage remained at the scene.
Police say the incident may have started with a confrontation at an event at a local park earlier. They are still trying to sort out the details.
The vehicles were heading northbound on Western Avenue near Palos Verdes Drive N., in San Pedro near the border with Lomita.
"We know there were multiple vehicles involved," said Los Angeles Police Department Capt. Michael Oreb. "It sounds like there were car-to-car shootings involved. There were people stuck by gunfire and they were transported to local hospitals."
Initial reports also indicated one of the victims was shot in the head.
