> (10-25) 22:13 PDT OAKLAND — Police fired tear gas at least three 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.”
> Protesters scattered in both directions on Broadway as the tear gas canisters and several flash bang grenades went off. Regrouping, protesters tried to help one another and offered each other eye drops.
