At 1:19 a.m., a tweet from Mayor Bloomber's office signaled the oncoming police move: Occupants of Zuccotti should temporarily leave and remove tents and tarps. Protesters can return after the park is cleared. Police handed out fliers from Brookfield Properties, Owners of the park, that said the same, according to numerous published accounts.

By 2a.m., police, some wearting protective gear, had swept through the park under the glare of kleig lights to address what one police captain had announced was an increasing health and fire hazard, according to the New York Times. Many protesters left the park, but about 100 rallied to the kitchen area, where they made makeshift barricades and sang, We shall overcome, according to the Times. The paper cited police spokesman Paul J. Browne, who told the  Associated Press that police had arrested approximately 70. Some protesters had refused to leave and chained themselves together, he noted.

By 3 a.m., the park was cleared of protestors.Some, forced from the park, proceeded to march to Foley Square.
