OAKLAND, Calif. (AP) -- Oakland officials say police are in the process of arresting about 100 Occupy protesters for failing to disperse.
Police Sgt. Christopher Bolton says the arrests come after Occupy Oakland protesters marched through downtown Oakland a little before 8 p.m. Saturday, with some of the protesters entering a YMCA building in the city's downtown.
The arrests Saturday night come after 19 people were arrested in Occupy Oakland protests during the day.
Police used tear gas and "flash" grenades on the group Saturday afternoon after some demonstrators threw rocks and other objects at them and tore down fencing.
