The Los Angeles Police Department arrested 14 people late Monday in South Los Angeles, when members of a George Zimmerman protest began breaking windows and stomping on cars, reports the Los Angeles Times.

About 350 LAPD officers moved into the area around Crenshaw Boulevard, after the once-peaceful protest turned violent. The protest had begun in Leimert Park on Monday.

Members of the protest attacked a TV reporter and his cameraman, and stormed a Wal-Mart at Baldwin Hills Crenshaw Plaza where they threw merchandise on the ground and tried to break open jewelry displays.

In Oakland, a crowd of several hundred people briefly shut down traffic on Interstate 880 on Monday evening. A group of 100 scuffled with police after 11 p.m., reports the Oakland Tribune.
