Cops released surveillance photos on Saturday of a tattoo-faced suspect who slashed a man in the neck in a Times Square subway brawl.

The suspect, sporting a slim build, a ponytail and multiple facial tats, a beige jacket and blue hoodie, got into an argument with a 35-year-old man in the 49th St. subway station near Seventh Ave. just before 1 a.m. on Friday, cops said.

As things escalated, he slashed the other man on the left side of his neck with a box cutter, then fled out of the station.

No arrest has been made as cops are hoping someone recognizes the suspect from the surveillance photos.

The bleeding victim jumped on a southbound Q train and took it two stops to 34th St., where he exited and ran to a cop on patrol nearby and asked for help.

EMS rushed the victim to Bellevue Hospital, where he was in stable condition.

Cops did not immediately say what the two men were arguing about.
