A man was slashed with a razor early Friday in a Greenwich Village subway station, police said.

The 33-year-old victim was squabbling with a 22-year-old man in the mezzanine of the station, located at 6th Avenue and 14th Street, at around 8 a.m., when the argument took a violent turn, cops said.

That’s when the younger man whipped out a razor blade, and slashed the victim on the upper left arm, cops said.

The 33-year-old was taken to Lenox Hill Hospital with non-life-threatening injuries.

The 22-year-old was arrested at the scene, police said.
