The 45-year-old man was taken to a hospital in critical condition, and police said they took a person of interest into custody shortly after they arrived around 1:30 p.m. Authorities did not release the names of that person or the man who was injured.
The incident happened at a station under Manhattan’s Chelsea neighborhood, a little more than a mile (about 1.6 kilometers) from Tuesday night’s big New Year’s Eve celebration in Times Square.
