Police in New York were searching Sunday for a suspect who allegedly stabbed another man to death on a city subway.

Police say the incident occurred shortly after midnight on a northbound 2 train at Penn Station.

A preliminary investigation has concluded that the assailant stabbed the 32-year-old victim in the neck in an unprovoked attack. The suspect then fled through the station and remained at large Sunday.

The unidentified victim was taken to a hospital where he was pronounced dead.
