Occupy Wall Street protesters crossed the Brooklyn Bridge on Sunday to mark six months since hundreds of them were arrested walking the same route.

Hundreds of activists marched from Manhattan's Zuccotti Park, where they first camped out last September to start a movement that has spread around the world. NYPD officers kept watch on scooters and on foot.

This time, the marchers used the pedestrian walkway to cross the bridge. The commemoration ended with a rally in Brooklyn's Cadman Plaza.

There were no reports of arrests.
