Police arrested more than 50 Occupy protesters in Portland while clearing out an encampment in two of the city’s parks Sunday afternoon. In Oakland, Calif. police have warned protesters that they must leave a plaza where they have camped out, the fourth such order in that city. As early Monday morning, law enforcement was preparing to move in on the camp if protesters did not clear. According to the Associated Press,

“Helmet-wearing officers from Oakland and several other San Francisco Bay area cities encircled the encampment at about 4:30 a.m. PST. Some held long sticks while others clutched white zip-ties.”

Though much of the attention has been focused on the standoffs in Portland and Oakland, similar tension could be seen at similar demonstrations across the country. CNN has a roundup of developments at Occupy protests in Denver, Honolulu, New York, Oakland, Philadelphia, Portland and Salt Lake City.

The protests began in New York’s Zuccotti Park in mid-September, when demonstrators began decrying Wall Street and economic disparities. They have since expanded to other cities across the United States, posing a challenge for municipalities where encampments have been set up in public spaces.
