A man has been arrested for a fatal stabbing inside a Manhattan homeless shelter, police said.

The deadly episode unfolded shortly after 2 p.m. Saturday inside a room at The Christopher on West 24th Street in Chelsea, police said.

The victim, 62, was stabbed once in the torso following a dispute, cops said. He was rushed to Lenox Hill Hospital and pronounced dead shortly before 3 p.m., police said.

A 59-year-old man was arrested at the scene and charges are pending.

Cops also recovered a weapon at the scene, an NYPD spokeswoman said. The names of the victim and suspect were not immediately released.

Christopher, 22, who stays at the shelter, said the attack happened at “Breaking Grounds,” where the men are a bit older

“That stuff happens here. A shelter is supposed to be a place where people put their head. They have nowhere to go,” he said. “The streets are already dangerous enough as it is. People are looking for just a safe place to go but when a safe place you can go ends up with people getting injured, it makes it scary.”

Another resident, Bernard, said of the shelter: “They don’t let us know nothing. I had to put the puzzle together.”

The man believed to be the suspect had lived at the shelter for a decade, said a woman who gave her name as Lizzy.

 “I’m really shocked…He’s not aggressive. This is mind blowing,” she said outside The Christopher. “Someone must have aggravated him. He’s a nice guy.”

The suspect’s brother was killed last year, said Lizzy, who noted “it took a toll on him.”
