11:05 PM--Between 200 and 300 protesters were arrested today at the downtown Occupy Oakland protests, including at least one journalist, Gavin Aronsen from Mother Jones.  Aronsen was caught in a "kettle" with roughly 130 protesters and journalists; other press were allowed to leave or be "unarrested;" it is thought Aronsen was taken to Santa Rita Jail. As of 11 PM, arrests were reportedly continuing. As in the last round of protests involving police brutality, protesters are complaining that many police are obscuring their badges, a violation of the California Penal Code, which states "Any uniformed peace officer shall wear a badge, nameplate, or other device which bears clearly on its face the identification number or name of the officer."

Police tear-gassed protesters and possibly shot rubber bullets at them during the late afternoon protests downtown; some reports that protesters entered the Oakland YMCA say that demonstrators were trying to get away from brutal police, not trying to occupy the building. “From their own posts and their letter to the Mayor and City Council, the demonstrators’ stated intention was to provoke the police and engage in illegal activity,” said City Administrator Deanna J. Santana, in a prepared statement.

Mayor Jean Quan characterized protesters as"a violent splinter group of the Occupy Movement" who were "engaging in violent actions against Oakland," and said  “The Bay Area Occupy Movement has got to stop using Oakland as their playground.”

Police from the Alameda County Sheriff’s Office and the cities of Fremont, Hayward, Berkeley, Pleasanton and Union City/Newark came in as part of a mutual aid request.

8:13 PM, January 28--More than 35 police--possibly some from other areas called into Oakland under a mutual aid request--are massing in front of City Hall, where occupy Protesters have broken into the building and are occupying it. Dressed in full riot gear, the police are massing to clear the building. Some Twitter stream news is saying documents are being tossed from the windows, other reports say police are blocking more protesters from entering. The crowd is pushing away mainstream media; our reporter says a demonstrator pushed the mike out of a KGO reporter's hand.
