A argument between two men turned into a gory knife fight that left one wounded in a popular Manhattan park, police said Friday.
The combatants got into it about 11:30 p.m. Thursday inside bucolic Riverside Park, a long stretch of green at Riverside Drive and W. 84th St.
Daniel Shasteen, 34, stabbed in the 59-year-old victim one in the neck, leaving him in critical condition, cops said.
Medics rushed the victim to a local hospital.
Shasteen was arrested at the scene and charged with assault and weapons possession.
Police said his motive for stabbing the victim was not known.
