About 50 Occupy Wall Street protesters marched in New York on Tuesday to demand the resignation of the city's police chief after a slew of arrests.
Several of the demonstrators knelt down, their mouths covered with tape and their hands tied behind their back in front of the headquarters of the New York Police Department in southern Manhattan.
NYPD chief Raymond "Kelly must resign," read a banner before the procession.
New York police arrested dozens of protesters at the weekend at Zuccotti Park in Manhattan's financial district, where about 600 activists had gathered to celebrate the six-month anniversary of the Occupy movement by massing on the square.
OWS said there were 90 arrests and five people were hospitalized after the police action. Many of those arrested were still held on Tuesday.
