NEW YORK (CBSNewYork) — The manager of an Upper West Side transitional housing facility was stabbed following an altercation with a male resident on Friday afternoon.

Police say that the 40-year-old manager was confronting the male resident about whether he had the proper papers to live in the building when the man attacked, stabbing the victim in the chest.

One female resident was saddened and shocked by the news.

“Its not right because he would even feed you and he’s not supposed to. He would give you money, and he would give you anything off his back,” she told WCBS 880’s Marla Diamond.

Another resident said that the alleged stabber was a known drug addict, and may have been under the influence at the time of the attack.

“He had been on drugs, I think like crystal meth,” the man said.

The manager was rushed to St. Lukes-Roosevelt Hospital, where he is being treated for his injuries.

The suspect was arrested at the scene.
