(ROUGH CUT ONLY - NO REPORTER NARRATION) Police wearing helmets and carrying shields moved to evict protesters with the Occupy Wall Street movement early on Tuesday from the park in New York's financial district where they have camped since September. Authorities have declared that the continued occupation of Zuccotti Park poses a health and safety threat. A police spokesman said 15 people had been arrested for disorderly conduct. Protesters said about 50 to 80 people still remained in the park, many of whom had linked arms. Some people had also chained themselves to trees.
