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 were also fired into the crowd. 
At least 300 people were arrested.
The demonstrators had attempted to take over vacant buildings to use 
as their headquarters, they also broke into City Hall and tried to 
occupy a YMCA. Police spokesman Jeff Thomason told media most of the 
arrests came around 8 pm local time. Police took many protesters into 
custody as they marched through the city's downtown area, with some 
entering a YMCA building.
Officials say, at one point protesters 
began tearing down perimeter fences around the Henry J. Kaiser 
Convention Center, as some attacked police officers, throwing rocks, 
bottles and other objects. Police declared an unlawful assembly and used
 force, according to the Oakland Tribune newspaper.
While police 
were taking people into custody near the YMCA, about 100 officers 
surrounded City Hall, while others swept the inside of the building for 
protesters who had broken in. Inside the building, protesters burned 
flags, broke into an electrical box and damaged several art structures, 
according to Oakland Mayor Jean Quan.
“The City of Oakland 
welcomes peaceful forms of assembly and freedom of speech, but acts of 
violence, property destruction and overnight lodging will not be 
tolerated,” the press release by city officials stated. “The 
Oakland Police Department is also committed to facilitating peaceful 
forms of expression while protecting personal safety and property 
through ethical and constitutional policing.”
At the moment, the Occupy crowd in the city’s central square is being monitored by dozens of police officers.
Oakland
 has seen one of America’s largest and most vocal Occupy protests, with 
thousands of people attending since the demos started in October. Some 
300 people have been arrested since then. The Occupy Wall Street 
movement started in September in New York and claims to represent the 99
 per cent of Americans, who suffer from corporate greed and economic 
injustice.
