Hundreds of protesters marched from Union Square to Times Square yesterday in another demonstration against a grand jury's decision not to indict Ferguson, Missouri police officer Darren Wilson for the shooting death of unarmed teenager Michael Brown. In an attempt to sustain the momentum generated last week, activists urged high school and college students to walk out of class nationwide in solidarity.

Unlike their more lenient policing last week, the NYPD physically prevented activists from taking over the streets, using their scooters to keep them on the sidewalk, with mixed success. Demonstrators managed to march in the street anyway, and ultimately seven were arrested. A police spokesman says all those arrested were charged with disorderly conduct.

Photographer Ellen Moynihan and the NYCLU say journalists were among those arrested.

CAAAV, an Asian-immigrant advocacy group, was one of the organizers of yesterday's demonstration, and estimated that some 1,000 protesters participated in NYC.
