An unarmed Black teenager riding the subway in New York City was aggressively thrown to the ground and had guns pulled on him by police officers during last Friday’s rush hour, NBC New York reported.

The teen, later identified by the New York Police Department as 19-year-old Adrian Napier of Brooklyn, was riding the train when the incident occurred. A video captured by subway passenger Elad Nehorai on Twitter showed nearly a dozen officers rushing inside the subway car to arrest Napier.

Napier had his arms raised while police pointed their guns at him through the subway’s windows, according to the video. Other train riders scattered once they saw the police pointing their weapons.

The Washington Post reported that Napier said, “call my mom” to other subway riders before the police began swarming in to arrest him.

Nehorai, in an interview with The Washington Post, said police pointed their guns at multiple people before focusing on Napier.

“For a moment, they were kind of pointing guns at everyone who was in that vicinity,” he said.

NBC New York reported the officers were responding to a call about a subway passenger with a gun. The local outlet said the 19-year-old did not have a gun on him but was later charged with theft of services.

Witnesses told police officers that Napier was seen with a gun near Atlantic and Flatbush avenues, according to NBC New York. The police department also said Napier had fled into the Pacific Street subway station when officers approached him.

Napier allegedly jumped over the turnstile and ran onto a southbound train, NBC New York reported. His description was then sent to other officers on patrol, some of whom later arrested him.

Napier was taken into custody and arrested for jumping the turnstile and was charged with theft of service. An investigation revealed he was “wanted for questioning in regard to a past larceny,” a police statement read.

A woman named Yolanda Sangweni said on Twitter her sons were on the train car during the incident. She said the incident could cause long-standing trauma for her boys.

“How do we, as parents, even begin to speak to them about this kind of violence? You see the trauma we’re exposed to at a young age,” she said in her Twitter post.

Presidential candidate Julián Castro said on Twitter the police should not have used the kind of force shown in the video for the crime Napier was charged with.

“This man didn’t pay his subway fare—but is tackled by at least ten officers in a crowded station,” Castro wrote on Twitter Sunday. “Officers should be working to deescalate—not putting dozens of lives at risk over $2.75.”

NYPD officers have been involved in at least 11 fatal shootings so far this year, the New York Times reported.

Criminal justice advocates say arrests for fare evasion tends to target people of color, Vice News noted. New York City officials have countered that argument and have said that fare evasion costs the city millions each year, reported CBS New York.
