Police officers in riot gear line Frank H. Ogawa plaza after "Occupy Oakland" protesters were arrested
OAKLAND, Calif. -- A crowd of protesters that had gathered in front of Oakland City Hall amid a heavy police presence, scattered as authorities fired tear gas in response to rock throwing from some of the demonstrators.
The police action was the second such incident in as many hours. Officers in riot gear briefly dispersed a crowd heading back toward the downtown area where an Occupy Oakland encampment was dismantled earlier in the day.
Authorities are denying reports that they used flash bang canisters to help break up the crowd, saying the loud noises came from large firecrackers thrown at police by protesters.
The Tuesday evening skirmishes came after police removed about 170 demonstrators who had been staying overnight on a plaza outside City Hall for more than two weeks. City officials said 85 people were arrested in the morning raid.
