Police arrested nearly two dozen anti-Wall Street protesters in two different cities Saturday and
tensions mounted elsewhere as local officials stepped up pressure for demonstrators to abandon their encampments.
For the second time in as many days, Oakland city officials warned protesters Saturday that they do not have the right to camp in the plaza in front of City Hall and face immediate arrest.
The eviction notices come as officials across the country urged an end to similar gatherings in the wake of three deaths in different cities, including two by gunfire.
In Salt Lake City, police arrested 19 people when protesters refused to leave a park a day after a man was found dead inside his tent at the encampment.
Authorities in Denver forced protesters to leave a downtown encampment and arrested four people for interfering with officers who removed illegally pitched tents, said police spokesman Sonny Jackson.
Meanwhile, tensions were increasing late Saturday night in Portland, Ore., where Occupy protesters faced a midnight deadline to abandon an encampment at two adjacent city parks or face
Violence marked the protest in San Francisco Saturday where police said two demonstrators attacked two police officers in separate incidents during a march.
Police spokesman Carlos Manfredi said a protester slashed an officer's hand with a pen knife while another protester shoved an officer, causing facial cuts. He said neither officer was seriously
hurt, and the assailants couldn't be located.
Demands for Oakland protesters to pack up increased after a man was shot and killed Thursday near the encampment site.
``Your activities are injurious to health, obstruct the free use of property, interfering with the comfortable enjoyment of (Frank Ogawa Plaza), and unlawfully obstruct the free passage or use of a public park or square,'' the notice read.
Police and a city official did not respond to requests for comment on whether police were preparing to forcibly clear the camp. Protesters said Saturday's peaceful march and rally in front
of City Hall was a show of solidarity with activists in Egypt.
Oakland officials first issued the eviction notice Friday after first pleading with protesters to leave the encampment.
Police officials have said a preliminary investigation suggested the shooting resulted from a fight between two groups of men at or near the encampment. Investigators do not know if the men in the fight were associated with Occupy Oakland, but protesters said there was no connection between the shooting and the camp.
The victim has not been identified.
The shooting occurred the same day a 35-year-old military veteran apparently committed suicide in a tent at a Burlington, Vt., Occupy encampment. Police said a preliminary investigation
showed the veteran fatally shot himself in the head. They said the death raised questions about whether the protest would be allowed to continue.
In Portland, Ore., Saturday, protesters with the movement dismantled large sections of their encampment amid a heavy police presence, but dozens of tents remained after nightfall and many
protesters appeared determined to remain.
Mayor Sam Adams ordered the camp shut down by midnight Saturday, citing unhealthy conditions and the encampment's attraction of drug users and thieves. Paramedics treated two people suffering from apparent drug overdoses, one on Friday and one on Saturday,
bringing to four the number of nonfatal overdoses inside the camp, police said.
Demonstrations rallied Saturday evening as organizers said they hope radical elements don't use violence to overshadow the movement's message of peaceful resistance to income inequality and what they see as corporate greed.
But police prepared for a possible clash, warning that dozens of anarchists may be planning a confrontation with authorities. Officers seized pieces of cement blocks Friday, saying they were
told some demonstrators had plans to use them as weapons against police. They said they believe some demonstrators are building shields and trying to collect gas masks.
The arrests in Salt Lake City came after police moved into the park early in the evening where protesters had been ordered to leave by the end of the day.
Authorities remained on the scene Saturday night as debris was cleared with a parks department front-end loader.
About 150 people had been living in the camp there for weeks.
Art Raymond, a spokesman for the mayor, said they have granted the protesters permits to maintain a 24-hour presence in the parks but will not allow camping.
City officials rescinded permits for the group to stay in the parks overnight Friday, about 12 hours after a man believed to be in his 40s was found dead inside a tent at the Occupy Salt Lake
City encampment, from what police said was a combination of drug use and carbon monoxide.
In Denver, where four people were arrested, police spokesman Sonny Jackson said police had advised protesters since Wednesday that their tents in Civic Center Park and on a nearby sidewalk were illegal. Some protesters blocked a nearby street, which riot police
quickly cleared. Police officers also doused a bonfire with a fire extinguisher.
Protesters have been marching in Denver for sixth straight Saturdays with dwindling numbers.
Meanwhile, in Southern California a small group of protesters braved soggy weather on Saturday to gather for the first time under the banner of Occupy Inland Empire. Members of Occupy movements in Fontana, Redlands, Riverside, and other nearby towns marched past
banks and in front of San Bernardino City Hall in what they called a ``visibility action,'' The Sun newspaper reported.
Protesters inspired by the Occupy movement also planned to camp over the weekend in Hendy Woods State Park in Mendocino County. The park is currently closed to camping, but about 150 to 200 people pitched tents Saturday.
The protesters want the state to keep the park open next year.
It is currently among 70 state parks slated to close under state budget cuts.
``This is really devastating to a lot of local people, a lot of local businesses,'' organizer Cyd Bernstein said.
