A man was stabbed in the stomach on a subway platform at Grand Central Terminal late Friday, authorities said.

Authorities say an argument aboard an uptown 6 train turned violent as the train pulled into Grand Central just before midnight.

As the subway doors opened, authorities say one man pulled out a knife and stabbed the victim, who was found minutes later by EMS shirtless with a knife wound to the torso.

The victim was taken to Bellevue Hospital with critical injuries, authorities said.

A man was taken into custody following the stabbing, but cops say no one has been charged yet as of Saturday morning.
