Steve Arnold, 30, of Union City was arrested after a photo on Snapchat was sent to his department, Fairview Police Chief Martin Kahn told Daily Voice.
"Arnold was not charged with the stabbing, only aggravated assault for his alleged role in the brawl," Kahn said.
Ex-con Michael A. "Money Mike" Agosto, 28, went to Bar One on Fairview Avenue looking for the victim just after 12:30 a.m. Sunday, Kahn originally told Daily Voice.
A confrontation led to an argument that quickly became a scuffle, he said
Suddenly, the victim felt a pain in his back.
He was taken to Hackensack University Medical Center with a non-critical stab wound, Kahn said.
Solid detective work led to a quick arrest, the chief said.
