PORTLAND, Ore. – 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 across the country and around the world.

In Portland, Ore., 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.

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.

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

Some protesters said they wanted to camp in the Pearl District because they see its residents as part of the wealthy demographic they’re protesting. Commissioner Randy Leonard had urged them to reconsider, saying in a letter that it would be inappropriate to expand the protest into a neighborhood park.

“We — the entire city council — are your friends … at present,” he wrote. “However, our friendship and support are now being unreasonably tested by the decision to occupy Jamison Square.”

Police in Austin, Texas, made 39 arrests early Sunday as they moved to enforce a new ban on food tables in the City Hall plaza where protesters have camped out. Some protesters surrounded the tables with arms linked.

Most were charged with criminal trespass, Police Chief Art Acevedo said. No injuries were reported.

“We want to facilitate their activities, but we can’t allow this to be a permanent campsite,” Assistant City Manager Michael McDonald told the Austin American-Statesman.

Some protesters found the ban arbitrary. “On a night where there are hundreds of drunks driving around town, they have all these resources here to take down three food tables,” protester Dave Cortez told the newspaper.
