OAKLAND, Calif - Crews cleaned up Oakland's historic City Hall on Sunday from damage inflicted overnight during violent anti-Wall Street protests that resulted in about 400 arrests, marking one of the largest mass arrests since nationwide protests began last year.
At a press conference on Sunday, Oakland police and city officials said they did not have a final tally of arrests. Earlier in the day, the city's emergency operations office put the figure at around 400. The skirmishes injured three officers and at least one demonstrator.Police said a group of protesters burned an American flag in front of City Hall, then entered the building and destroyed a vending machine, light fixtures and a historic scale model of the edifice. The city's 911 emergency system was overwhelmed during the disturbances.
