Police cleared an Occupy SF encampment in front of the Federal Reserve building in San Francisco overnight.
Riot police moved in on the encampment on the sidewalk at 101 Market St. at around 4 a.m. Sunday. Police said they gave campers several warnings that began Friday morning.
Police said they arrested 55 protesters were arrested for illegal lodging, and while interactions between police and protesters was tense, no officers or protesters were injured.
Police said some officers were spit on and one officer was pushed by demonstrators.
All of those arrested were taken away in zip ties and released before sunrise.
It was not immediately clear how the occupiers would respond to the arrests. The Federal Reserve encampment became the largest in the city after police raided the camp at Justin Herman Plaza last week.
