Police said he was stabbed in the left shoulder with a knife -- and that the puncture wound required "two sutures."

The alleged assault took place just after 12 a.m.

Police said Sanchez was arrested after being subdued by the victim and a taxi driver.

Police said the suspect and the victim first met each other at the train station and went to drink at a nearby bar. The victim told police that when the two returned to the station, he "began to assist the defendant onto the train" -- at which time the Sanchez "became physical and reportedly stabbed the victim with a knife."

No other details were immediately available.
