Dozens of anti-Wall Street protesters were arrested Sunday in Texas, where they clashed with police over food tables, and in Oregon, where officers dragged them out of a park in an affluent neighborhood. In New York and many other East Coast cities, it was a snowstorm that was making it difficult for demonstrators to stay camped out in public places.

The “Occupy” movement, which began six weeks ago in lower Manhattan to decry corporate influence in government and wealth inequality, has spread to cities large and small across the US and around the world. Demonstrators have spent weeks camped out in parks, wearing the patience of city officials — even those who have expressed some level of support for their cause.

Officers began clearing the park in Richmond around 1 a.m. and most of the protesters left when told to and around a dozen who stayed were arrested for trespassing, police spokesman Gene Lepley said.

The occupation had blossomed into a tent city, with dozens scattered around Kanawha Plaza in the city’s financial district. The site also included a library, a volleyball net and a large blue tarp strung up on three magnolia trees.

One of the protesters, Ira Birch, said the park was surrounded by a “huge line of cops” and police cruisers with their blue lights flashing. An officer read ordinances that the protesters were violating and told people to gather up their possessions and leave. She described the scene as “pretty peaceful.”

In Portland, Oregon, police have allowed protesters to sleep in two parks surrounded by office buildings despite policies outlawing camping, but Mayor Sam Adams warned demonstrators last week that he would not allow them to take over any more parks. Late Saturday, hundreds of protesters gathered in another park — Jamison Square in the wealthy Pearl District — and defied a midnight curfew.

About 30 people who had decided to risk arrest sat on the ground as other protesters walked around them and chanted “Whose Park? Our Park!” and “Make No Arrests.”

When police moved in around 2 a.m., all but the sitting protesters backed off. An Associated Press photographer said most of those protesters went limp and were carried or dragged away by police. There was no violence during the arrests, which took about 90 minutes.

The protesters — all appearing to be in their 20s and 30s with many wearing Halloween-style face paint — were handcuffed and taken away in police vans. “We are the 99 percent,” one arrestee continued to chant.

Police said the arrests were made on charges that included criminal trespassing, interfering with a police officer and disorderly conduct.

Also Sunday, the roommate of an Iraq War veteran seriously injured in a clash with police during an anti-Wall Street protest says Scott Olsen is doing well and doctors say he’ll make a full recovery.

Keith Shannon, who served with the 24-year-old former Marine in Iraq, told The Associated Press that he visited Olsen at a medical facility Sunday and he “seems to be doing well.”

Shannon says Olsen still can’t talk but doctors expect him to make a full recovery.

Olsen suffered a fractured skull and other head injuries during the clash Tuesday.

Police are investigating how Olsen was struck by a projectile.

Wall Street protesters around the country have rallied around Olsen’s plight.
