Two videos of violent arrests inside Brooklyn subway stations this weekend are sparking protests over police brutality, and some elected officials have called for an immediate investigation into the police officers' conduct.

The unrelated incidents—in which NYPD officers descended on a crowded train to arrest an unarmed man and, on a separate platform, punched multiple teenagers while breaking up a fight—happened less than 24 hours apart. The outcry over the arrests comes amid growing scrutiny into an effort to clamp down on low-level subway offenses by nearly doubling the number of cops in the transit system.

The first confrontation occurred as a rush hour train pulled into Franklin Avenue on Friday evening. A video posted online shows officers gathering outside the stopped train and allegedly pointing their guns through the windows. As riders nervously flee the area, the suspect raises his hands in the air and directs a passenger to call his mother. The doors open moments later, and more than a dozen officers storm the train, tossing the suspect on the ground and cuffing him.

“It was so aggressive and dangerous,” said Elad Nehorai, a Crown Heights resident who took the video. “They’re pointing guns at a train full of high school kids and other bystanders. If any small thing had gone wrong someone could have been hurt or killed really easily.”

In a statement, an NYPD spokesperson said that cops were responding to a tip about a man with a gun. Officers chased a 19-year-old suspect into Pacific Street subway station, where police said he hopped the turnstile and boarded the 4 train. The man was unarmed when police arrested him, and was charged only with theft of services for fare evasion.

Nehorai, who works in marketing and serves as a spokesperson for the progressive Orthodox Jewish group Torah Trumps Hate, told Gothamist that cops attempted to block bystanders from filming the scene. Throughout the ordeal, he said, passengers on the train were far more afraid of police than the 19-year-old, who was “clearly cooperating and scared.”

“Seeing all the other young black men who were worried for their own safety when they hadn’t done anything wrong—this is something that has reverberations,” he added.

Another tense confrontation unfolded on the platform at Jay-Street—Metrotech on Saturday afternoon, where police say they were responding to a fight between two groups. The chaotic video begins as cops attempt to apprehend young members of the group, some of whom are not cooperative.

After a few seconds, a white officer charges at a young black man and punches him in the face, prompting cries of shock from the crowd. The same cop then rushes at another person, who’s not involved in the scuffle at that point, and swings at his head. The target of the punch pushes the officer, and he’s wrestled to the ground by eight cops.

“He didn’t even do nothing,” shouts one of the witnesses.

A spokesperson for the department said “the situation escalated” after someone attempted to interfere with police action. “Publicly available video does not show the entirety of the incident, and the department is conducting a review,” the NYPD’s communications arm noted on Twitter.

Four people were arrested and one juvenile report was prepared, police said. Additional questions about the incident were directed to the Brooklyn District Attorney’s Office, which did not provide details by press time. According to the Post, a 15-year-old was charged with assaulting a police officer, a 16-year-old was charged with reckless endangerment, and three 18-year-olds were charged with resisting arrest.

Brooklyn Borough President Eric Adams has called for the officer seen punching two teenagers to be placed on modified duty and for the department to conduct an immediate investigation into the incident. “As a former police officer, I know that one of the most difficult parts of policing is interacting with young people amid a dispute,” Adams said in a statement. “This is another clear example of why deescalation training matters.”

On Monday afternoon, a coalition of advocates and elected officials, including State Senator Julia Salazar and Councilmember Antonio Reynoso, will hold a press conference condemning the “hyperaggressive NYPD response and excessive force in Brooklyn train stations" this weekend.

One of their demands is that Governor Andrew Cuomo cancel the hiring of 500 new MTA officers, a group that will be tasked with enforcing quality-of-life crimes such as farebeating. Hundreds of NYPD officers and MTA police have already been diverted from their existing posts into the subway system, at the governor’s urging.

The advocates are also urging Mayor Bill de Blasio to release the names of the officers involved in the arrests. Neither the Mayor’s Office nor the Governor’s Office responded to Gothamist’s inquiries.

Norman Siegel, a longtime civil rights attorney who previously led the New York Civil Liberties Union, said the two incidents should force the mayor and governor to acknowledge that training and supervision of police is largely falling short.

“Excessive force, abuse of authority, discourteousness has been and continues to be a problem with some NYPD officers,” Siegel said, particularly in police interactions involving young black men. “They’re not approaching young white students on the Upper West Side with guns drawn.”
