NYC Occupy Protest Results in 25 Arrests

Occupy Wall Street protesters are gearing up for a Monday demonstration to mark the first anniversary of the movement — and give the 1% a fresh headache.

Nearly 200 scruffy anti-capitalists swarmed Washington Square Park on Saturday in a warmup for Monday morning, when the activists will march on Wall Street and attempt to disrupt rush-hour traffic.

By late afternoon, tensions between activists and cops led to arrests, as a procession of protesters chanting "F--- the police!" marched down Broadway bound for Zuccotti Park, the movement's old base.
