Six people were injured in a knife attack at New York City’s Penn Station on Sunday, authorities said.

The city’s fire department said it received a call about someone stabbing multiple people at the major intercity railroad station in midtown just after 7 p.m.

One person had serious injuries, and other injuries ranged from minor to moderate, the fire department said. Those people were taken to Bellevue Hospital, while a sixth person with a minor injury was taken to Cornell Hospital, it said.

An Amtrak spokesperson said that five people were slashed but that all patients were stable. A knife was recovered at the scene, the spokesperson said.

Amtrak police took a person believed to have mental health issues into custody, a senior law enforcement official said, adding that there are no preliminary signs the attack was related to terrorism.

Mayor Zohran Mamdani said he was briefed on the stabbing, and he praised Amtrak police for their “swift response.”

“My heart is with everyone who was injured, their loved ones, and all those shaken by this unacceptable violence. I’m wishing each of the victims a full and speedy recovery,” he said on X.

He noted there were no impacts to Amtrak service.

New York Gov. Kathy Hochul condemned the attack, calling it “an act of horrific violence.”

“Our hearts are with the victims and their loved ones, and we are praying for their full recovery,” she said on X. “New Yorkers deserve to feel safe wherever they go, and we will never stop working to make that a reality.”
