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.
