Arrests at Occupy L.A. raise concerns for organizers, LAPD

Occupy L.A. organizers said they are working to address security issues after several arrests.

Protester Orameh Bagheri said the camp's safety committee is working on how to address acts of aggression, which she said are an anomaly. "It is a nonviolent movement," she said.

A woman was arrested at the encampment outside City Hall after she set another person's clothes on fire, police said. In another incident hours later, a woman was arrested after protesters said she struck a man with a tent pole. Both were booked on suspicion of assault with a deadly weapon.

Also Friday, police arrested a man on suspicion of climbing a tree and dumping fluorescent paint on a historic marble fountain that the city barricaded earlier this week to protect from vandalism.
