Millions March

There have been at least a dozen arrests so far.

Four others involved in the Brooklyn Bridge confrontation have already been arrested.

Another protester has been arrested in connection with the incident in which two police officers were assaulted during the Millions March NYC on the Brooklyn Bridge.

One of the protesters who was allegedly part of a group that assaulted two police officers during the Millions March NYC on the Brooklyn Bridge last weekend has turned himself in.

And the group "Citizens Outraged at Police Being Shot" is offering a $10,000 reward.

"Do the people marching know what they're marching for?" one Santa wonders.

A 29-year-old CUNY professor has been arrested for allegedly assaulting two officers at last night's Million March NYC.

The NYPD estimated the crowd of the Millions March to be between 20,000 and 30,000, while the march's organizers say the number is closer to 50,000.
