Police are looking for a man who was wearing a medical mask when he spat on and slashed a cab driver in Manhattan early Saturday morning.

An argument over the cab fare preceded the assault, which occurred about 2:20 a.m. at the intersection of East 59th Street and 3rd Avenue in Lenox Hill, authorities said.

The suspect, who was also wearing blue gloves, cut the 41-year-old cab driver on his right hand with an unknown object, police said.

The victim was taken to NewYork-Presbyterian/Weill Cornell Medical Center for treatment.

The suspect fled after the attack. He was captured by surveillance cameras inside the Lexington Avenue – 63rd Street station.
