The New York Police Department urged travelers to avoid Grand Central Station on Saturday, citing a police investigation.

NEW YORK CITY, N.Y. — Police in New York City shot a man who was reportedly armed with a large knife after they received calls that several people were stabbed Saturday at a subway station. 

New York police officers responded shortly before 10 a.m. Eastern to the scene at Grand Central Station, where they encountered the man on a station platform.

A law enforcement official not authorized to discuss the investigation publicly told the Associated Press the large knife was described as a machete. 

Police then shot the man, who survived. He was brought to the hospital, where he was listed in critical condition, according to the agency. 

Three people were stabbed during the incident, according to police, and all were expected to survive. They were identified only as an 84-year-old man, a 65-year-old man, and a 70-year-old woman. 

Two police officers were also evaluated at a hospital, according to the Associated Press. 

The New York Police Department asked travelers to avoid Grand Central Station in a post on X, citing a police investigation, and the Metropolitan Transit Authority confirmed several subway trains were not stopping at the station. 

A spokesperson with the New York Police Department said it would be releasing updates about the investigation at a later time.
