On the first of three days of events planned for the one-year anniversary of Occupy Wall Street, about 250 people marched down Broadway from Washington Square toward Zuccotti Park, accompanied by a large number of police officers on foot, in marked and unmarked cars, and riding scooters.

At two points along the way, police officers plunged into the crowd and made arrests on sidewalks. Further arrests followed after the crowd reached its destination. In all, it appeared that at least 15 people were taken into custody. Police officials could not immediately provide information about how many people were arrested and with what they were being charged.

The first arrests took place around 6:30 p.m. on Broadway near West 4th Street. Witnesses said that marchers were on the sidewalk on the west side of Broadway when officers grabbed one young man who may have been wearing a bandanna mask and pushed him against the wall.
