Demonstrators stand on subway tracks in Manhattan, stopping trains and fighting with police in protest

Protesters brought part of New York’s Manhattan subway system to a standstill by venturing onto the tracks as they expressed anger at Jordan Neely’s death from a stranglehold by a US Marine earlier this week.

Photos and videos show the protest group taking control of the Lexington Avenue and 63rd Street subway station on the Upper East Side, bringing trains to a standstill.

Several people even walked onto the tracks near the electrified third rail to prevent the train from entering or exiting the station.

The protesters marched from downtown to the Upper East Side before descending into the subway system to stop the trains themselves.

This resulted in the station’s complete closure for the better part of an hour, with the NYPD arresting at least 15 people.

Some of the protesters standing on the tracks held protest signs.

A person stood atop the protective shell that shields the electrified third rail, which normally carries 600 volts of electricity.

Police made numerous arrests when trains on lines F and Q were held up for nearly an hour from 6:15 p.m. The service is said to have resumed at 7 p.m.

The death of 30-year-old Neely on Monday has sparked an outcry over the city’s lack of support for people with mental illness and homelessness.

Activists are calling for charges to be brought against the Marine veteran at the center of disturbing video of Neely in a chokehold on the floor of a northbound F-train.

Neely died from compression of his neck, the city’s coroner found on Wednesday.

He was screaming while pacing on a train in Manhattan on Monday afternoon when he was restrained by at least three people, including the Navy veteran, who had an arm tight around his neck.

A physical struggle ensued, during which Neely lost consciousness.

He was taken to Lenox Hill Hospital where he was pronounced dead.

Neely is recognizable to some New Yorkers as a Michael Jackson impersonator who regularly danced in the transit hub of Times Square.

Dario agreed and said ¿100 percent [Penny should at least be charged]¿ Regardless of his reason or logic as to why this happened at the moment, we need due process.  ¿

The former Marine who put homeless man Jordan Neely in a deadly chokehold on the New York City subway has been officially identified as Daniel J. Penny (right).

Penny can be seen holding him for 45 seconds even after Neely appears to have gone limp, and as a viewer warned:

The Marine in question, Daniel Penny, 24, has not been charged with a felony in connection with Neely’s death.

Multiple reports suggest that Manhattan District Attorney Alvin Bragg could convene a grand jury and indict as soon as next week.

ABC News notes that it is “typical” for prosecutors to take their time in complex cases before calling a jury.

Detectives in the case have spoken to about six witnesses who saw the disturbance and are trying to speak to about four or five others.

Penny was also interrogated by the police and released. He reportedly said he had no intention of killing Neely and tried to hold him until police arrived.

Witnesses said that around 2:30 p.m. last Monday, Neely, who relatives said was schizophrenic, was behaving erratically, throwing garbage and screaming that he wanted to “die” or “go to jail” because he was fed up with to have nothing to eat.

Video footage shows Penny with Neely in a chokehold. For two minutes and five seconds, Neely struggled on the ground, kicking his feet. After two minutes and six seconds he went limp.

The police took Penny into custody. But he was later released and has not been charged.

In the statement, Penny’s attorneys say the Long Islander “couldn’t have predicted [Neely’s] untimely death.’ It also said Penny was merely trying to detain Neely, who was accused of disrupting aboard an F-train, until police arrived.

Neely’s attorneys also targeted “elected officials,” urging them to “address the mental health crisis on our streets in subways.”
