Police raid Occupy D.C. encampment WASHINGTON, Feb. 4 (UPI) -- U.S. Park Police raided an Occupy D.C. encampment in Washington and arrested four people Saturday, authorities said. Officers on horseback and on foot with riot gear cleared some tents and debris after entering McPherson Square about 6 a.m., The Washington Post reported. Those arrested had refused to leave an area in the center of the park where workers were trying to clear tents, bedding and debris. David Schlosser, a spokesman for the U.S. Park Police, said in a statement parts of the park were being closed for "nuisance abatement." "This is not an eviction," Schlosser said. But protesters said it was an eviction. "We're being evicted without tear gas," said Melissa Byrne, a protester from the district. Police said a week ago they would begin enforcing rules that allow protesters to have a 24-hour vigil in the federal park but not camp overnight.
