Police in Oakland, California, have used tear-gas and flash-grenades as a 2,000-strong Occupy Oakland march turned violent, with some protesters claiming that rubber bullets had been also fired into the crowd. At least 300 people were arrested, police say.
The demonstrators attempted to take over a vacant building to use as their headquarters. As they began tearing down perimeter fences around the Henry J. Kaiser Convention Center, police declared an unlawful assembly and used force, according to the Oakland Tribune newspaper.
