A 49-year-old man was stabbed during an early-morning clash when he bumped into a stranger just outside the Port Authority subway station Friday, authorities said.
Guarionex Torres was knifed in the neck and groin after he and Jesus Ramirez, 28, got into a fracas at West 44th Street and Eighth Avenue in Hells Kitchen just before 1 a.m., according to cops.
Torres was rushed to Bellevue Hospital, where he was pronounced dead.
Ramirez was arrested on the scene and charged with murder and criminal possession of a weapon, police said.
He is claiming self-defense, according to police sources.
Torres has multiple prior arrests and was busted just last week for swinging a hatchet at people, cops said.
A knife was recovered near the scene, cops said.
Brass knuckles were also recovered, police sources said.
Photos show a Citi Bike on the ground near the taped-off scene.
