Man shot on New York City subway after physical altercation

A 36-year-old unidentified man is currently in critical condition after being shot by another man on the New York City subway, according to authorities. 

The victim is currently in surgery and the suspect is currently with detectives, NYPD's chief of transit Michael M. Kemper said during a news conference. 

The incident reportedly happened during rush hour on Thursday around 4:45 p.m.

"There were multiple police officers in this station just feet away from when the train pulled in, who heard the shots and moved in right [a]way," Kemper said, according to ABC News.

No one else has been injured in the incident. 

The 36-year-old was shot after the suspect got "aggressive and proactive" with him as the train was pulling into a station.
