A teenage boy has been arrested in connection with an attack on another teen at a Manhattan subway station, the NYPD said Wednesday.

The 14-year-old boy faces assault, aggravated harassment, harassment and menacing charges stemming from the Friday assault, police said.

According to the NYPD, authorities are still searching for other suspects in connection with the attack, but it is unclear how many people are being sought.

Police said a group of people approached a 15-year-old boy with autism inside the 181st Street A train station in Washington Heights around 5:30 p.m. on Friday and pulled him from a train onto the platform.

The group then attacked the boy after making anti-Black statements, striking his head and body several times before fleeing the station, the NYPD said.

Emergency responders took the boy to NewYork-Presbyterian/Columbia University Irving Medical Center, where he was treated for a cut to his lip, as well as pain and bruising to his body, police said. He was listed in stable condition after the attack, according to police.

The NYPD said its Hate Crime Task Force is investigating the incident.

In a statement released Tuesday, New York City Transit president Richard Davey called a video of the attack that went viral on social media "heartbreaking and disturbing," adding that "our hearts are with the young man seemingly being senselessly victimized."

"No one should be subject to this sort of hateful harassment while they are riding with New York City Transit, and the MTA is fully cooperating with the NYPD in its investigation into this incident," Davey said.
