Shopkeepers in trendy Westwood swept up broken glass, boarded up windows and calculated looting damage Saturday left by hundreds of rioters who went on a rampage after a movie theater oversold tickets for the film "New Jack City."

Police estimated up to 1,500 people joined the 2 1/2-hour melee Friday in the bustling movie, dining and shopping district fronting the University of California, Los Angeles campus, Lt. Douglas Pilot said."It was out of control for a while," Pilot said. "Looters were seen battering people, knocking them down as they went."

Nine people were booked for investigation of looting.
