At a press conference last night, NYPD Commissioner Bill Bratton displayed screengrabs of six suspects seen tussling with police in video filmed on the Brooklyn Bridge during Saturday night's Millions March. The fight started after two lieutenants from the NYPD Legal Bureau, Philip Chan and Patrick Sullivan, approached a man holding a garbage can. Suspecting that he intended to throw it on officers patrolling the bridge below, they stopped him and attempted to make an arrest. That's apparently when other demonstrators intervened, as seen on this video from photographer Chris Nooney:

Police say the man with the garbage can, a CUNY adjunct professor and poet named Eric Linsker, was the one seen in the video resisting arrest and eventually escaping. Linsker allegedly left a backpack containing hammers, his CUNY ID, marijuana, and his passport behind, and he was arrested by members of the NYPD and FBI's Joint Terrorism Task Force shortly before 4 a.m. on Sunday.

Linsker is charged with robbery, resisting arrest, reckless endangerment, obstructing government administration, and unlawful possession of marijuana, as well as two felonies: assault on a police officer and inciting a riot in the first degree. Bratton told reporters last night, "We do not take attacks on our police officers lightly. Never have; never will."

Police say that during the melee one protester broke Lieutenant Chan's nose, and another kicked Lieutenant Sullivan. Bratton said that enhanced images of the other suspects would likely be released soon.

Bratton also said that some 331 protesters have been arrested since the start of large-scale demonstrations following grand jury decisions not to indict officers who killed Eric Garner on Staten Island and Michael Brown in Missouri. Six of those arrested were charged with assaulting NYPD officers. Bratton also said that since December 3rd, the city has spent $22.9 million in police overtime related to the protests.
