Encampments of protestors in New York and Oakland, both part of the Occupy Wall Street Movement, were raided by police Monday and cleared of demonstrators, tents and garbage. Officials in both cities said the camps posed health and safety concerns for the protestors and nearby residents. Police cleared the Occupy Wall Street camp in Lower Manhattan’s Zuccotti Park, birthplace of the Occupy movement, Monday. About 180 to 190 demonstrators in the park were arrested, according to The New York Times. At a news conference Tuesday, Mayor Michael Bloomberg said the park needed to be cleared because “health and safety concerns had become intolerable.” Protestors have been camped out in the park for two months.
