The video begins with fists flying between two men aboard the subway. Several passengers can be seen aboard the train watching as the fight intensifies. In short order, the Asian man is pinned against a subway bench, and the attacker keeps throwing punches. Finally, the attacker puts the Asian man in a chokehold. At that time, passengers can be heard calling for the attacker to stop. The Asian man passes out, and the attacker bashes his head against the subway seat before getting off the subway.

New York City Transit Interim President Sarah Feinberg called the video “absolutely horrifying and gut wrenching.”

“We have offered our assistance to the NYPD and we will do anything we can to assist them with their investigation,” Feinberg said in a statement. “Racist, criminal behavior targeting Asian Americans is horrifying, and it must stop.”

The video was released amid an alarming spike in anti-Asian violence in New York City and beyond. On Monday, a rally against anti-Asian hate was held in Bensonhurst.
