Three men were hauled-off in handcuffs after a wild broad-daylight stabbing on the Upper East Side that occurred outside a tony Madison Avenue restaurant on Friday afternoon.

Police say it all began just before 2:30 pm when a 45-year-old Rueben Medina got into an argument with two men, 57-year-old Luis Ramos and an unidentified 23-year-old man, near the corner of East 65th Street and Madison Avenue.

The dispute turned physical with Ramos and Medina exchanging blows in the street, punching each other in the face and head, according to investigators. At some point during the scuffle, Medina was stabbed in his left arm just above the elbow, police say.

As Ramos and Medina were being treated by paramedics, a man believed to be the 23-year-old, returned to the scene and lunged at the stabbing victim, who was already handcuffed and being held by an NYPD officer.

Nine cops were needed to subdue the man in a shocking scene just steps from Match 65 Brasserie where, diners sitting outdoors for lunch witnessed the violence that unfolded.
