A verbal argument led to a stabbing inside a Baldwin bar on Thursday that left the victim with a neck wound requiring stitches, police said.
Nassau County police said investigators are searching for a suspect.
The attack occurred at the Oasis Bar on Brooklyn Avenue at about 8:30 p.m. It was not clear what sparked the incident, which police said began with "a verbal argument" -- then led to a stabbing.
