A man was stabbed on board a PATH station as it departed the 23rd Street station, authorities say.
Port Authority officials say a man stabbed the 38-year-old victim in the chest as the train was traveling between the 23rd and 33rd street stations on Sixth Avenue.
The suspect fled once the train pulled into 33rd Street.
It's not clear if the victim and the suspect knew each other.
The victim was taken to Bellevue Hospital and is expected to survive, officials said.
