A day after a Staten Island grand jury refused to indict a police officer who put an unarmed black man in a fatal chokehold, protesters are back on the streets. Thousands—one report says over 7,500—have gathered at Foley Square in lower Manhattan.

This follows last night's protests which saw streets and highways in Manhattan shut down. Some protesters are marching across the Brooklyn Bridge, forcing the NYPD to close Brooklyn-bound lanes.

The protest is breaking into a number of groups and spreading out—a couple thousand at the bridge, a few thousand heading to the West Side highway and around 4,000 at Chambers and Broadway.

Another protest is planned for Sara D. Roosevelt Park on the Lower East Side; organized by the Trayvon Martin Organizing Committee NYC.

Update: One group of protesters is now at the Holland Tunnel, shutting down part of Canal Street.
