A man was slashed in the neck with a razor during a squabble in a Manhattan subway station early Monday, according to authorities and police sources.

The 35-year-old victim got into a fight on the B/D/F/M train platform of the 34th Street-Herald Square station just after midnight when his rival slashed him on the left side of the neck and took off, authorities said.

The man was taken to NYC Health + Hospitals/Bellevue with non-life-threatening injuries.

His attacker, who police sources said may be homeless, remains at large.

He is described as in his 30s, around 5-foot-10 and 160 pounds, last seen wearing a black T-shirt, gray jeans and carrying a black trash bag, the sources said.
