Chaos At Occupy Oakland

San Francisco Chronicle:

Police fired tear gas at least five times Tuesday night into a crowd of several hundred protesters backing the Occupy movement who unsuccessfully tried to retake an encampment outside Oakland City Hall that officers had cleared away more than 12 hours earlier. Police gave repeated warnings to protesters to disperse from the entrance to Frank Ogawa Plaza at 14th Street and Broadway before firing several tear gas canisters into the crowd at about 7:45 p.m. Police had announced over a loudspeaker that those who refused to leave could be targeted by "chemical agents."

Tear gas and flash grenades were eventually used.
