Reuters reports:

Police dismantled a tent city of Occupy protesters in downtown San Francisco early on Wednesday, arresting more than 50 as they shut down the last major Occupy encampment on the West Coast.

The city had repeatedly warned the protesters to move from the public plaza at the foot of Market Street in recent weeks and tried unsuccessfully to negotiate a move to another location. Read the full story.

Police officers hold the line outside the Federal Reserve Bank on Dec. 1, 2011.

Police erected barricades on Thursday around a San Francisco park where hundreds of anti-Wall Street protesters braced for eviction two days after failing to agree to a city plan for relocating their camp.

Occupy San Francisco is believed to be the largest of a dwindling number of West Coast protest settlements aligned with the national movement protesting economic inequality, after a larger group in Los Angeles was evicted earlier in the week.

The purpose of the barricades put up at the plaza was not immediately clear, but most police officers left after they were installed, and a raid there did not seem imminent.

Shortly after police installed the barricades along three sides of the park, protesters bandied together to haul away the fencing from one side as more than a dozen officers stood by watching. Protesters then chanted "Cops go home." Read the full story.
