A 31-year-old man was slashed in the face during a squabble with three suspects in a Manhattan subway station early Monday, cops said.

The victim was involved in an argument with the trio — all believed to be homeless — on the 6 train platform at Lexington Avenue and East 116th Street in East Harlem around 3:30 a.m., police said. 

The victim was taken to Harlem Hospital with non-life-threatening injuries. 

The suspects — three men ages 38, 42 and 55 — were arrested on scene. Charges are pending. 

No details were immediately available on what led to the dispute.
