Police arrest 75 protesters at Oakland's City Hall

Police in riot gear cleared anti-Wall Street protesters from in front of Oakland's City Hall on Tuesday morning, leaving a sea of overturned tents, protest signs and trash strewn across the plaza.

Hundreds of officers and sheriff's deputies from more than a dozen agencies went into the two week-old encampment with tear gas and beanbag rounds at around 5 a.m., police said. Seventy-five people were arrested, mostly on suspicion of misdemeanor unlawful assembly and illegal camping.

About 170 protesters were at the site, but no one was injured, according to police.

"I'm very pleased with the way things went," Interim Oakland Police Chief Howard Jordan said at a news conference following the raid.

Television news footage showed protesters being taken away in plastic handcuffs without incident, though some protesters complained of rough handling by police.

Officers fired tear gas and bean bags when one group of demonstrators pelted officers with rocks and bottles near the camp's kitchen area, Jordan said.

"It was definitely chaos. People didn't want to get gassed," said protester Anthony Owens, 40, a computer programmer from Oakland who was at the scene when police moved in but was not arrested.

Some people in the camp left as word spread about possible police action, Owens said. Many of the remaining protesters locked arms and shouted as officers surrounded the plaza and moved in.

Witnesses reported seeing smoke rising from the area. The plaza was "contained" at around 5:30 a.m., city officials said.

The Oakland site was among numerous camps that have sprung up around the country, as protesters rally against what they see as corporate greed and a wide range of other economic issues. The protests have attracted a wide range of people, including college students looking for work and the homeless.

In Oakland, tensions between the city and protesters escalated last week as officials complained about what they described as deteriorating safety, sanitation and health issues at the site.

City officials had originally been supportive of protesters, with Oakland Mayor Jean Quan saying that sometimes "democracy is messy."

But the city later warned the protesters that they were breaking the law and couldn't stay in the encampment overnight. They cited concerns about rats, fire hazards, public urination and acts of violence at the site, which had grown to more than 150 tents and included areas for health care, child care and cooking.

"Many Oaklanders support the goals of the national Occupy Wall Street movement," Quan said in a statement on Tuesday. "However, over the last week it was apparent that neither the demonstrators nor the City could maintain safe or sanitary conditions or control the ongoing vandalism."

There were reports of a sex assault and a severe beating and fire and paramedics were denied access to the camp, according to city officials, who said they had also received numerous complaints of intimidating and threatening behavior.

Protesters disputed the city's claims about conditions at the camp. They said the protest was dominated by a spirit of cooperation that helped keep the site clean and allowed disputes to be resolved peacefully.

Lauren Richardson, a 24-year-old college student from Oakland, complained that the disheveled state of the camp following the police raid gave a false impression. She said volunteers collected garbage and recycling every six hours, that water was boiled before being used to wash dishes and that rats had infested the park long before the camp went up.

"It was very neat. It was very organized," Richardson said.

Volunteers at the medical tent erected on the site said paramedics had not been kept away.

On Thursday, the city ordered the protesters to vacate, though they did not set a deadline. Protesters said the number of people at the camp had steadily dwindled since the city posted the letter, while those who remained understood they would likely face a confrontation with police.

After Tuesday's raid, police maintained a heavy presence around downtown Oakland. Streets were closed off by police barricades, and at least two helicopters were in the air shining lights down. Dozens of officers were on the streets, and police in riot gear were seen facing off with shouting protesters, who briefly blocked traffic on a busy thoroughfare.

City officials advised downtown businesses to delay opening and city employees to come in late.

Police also cleared a smaller encampment from a park near the plaza on Tuesday morning.

The city said protesters would be allowed to return to the plaza after it was cleaned up and could stay between the hours of 6 a.m. and 10 p.m. but not overnight.

Many protesters said the raid had only served to strengthen their resolve that the protests would continue. A flier handed out along the police barricades at the edge of the plaza Tuesday morning asked Occupy Oakland demonstrators to reconvene at the city's public library in the afternoon.
