Riot police arrest 15 at New York's Occupy protest

The New York mayor has sent in police in riot gear to remove protestors camped out in the financial district, but they have been told they can return once the area has been cleaned.

At about 1am local time today, police handed out notices from the owner of Zuccotti Park, Brookfield Office Properties, and the city saying that the park had to be cleared because it had become unsanitary and hazardous.
