Three off-duty New York City employees were busted early Saturday in unrelated incidents — two for assault and another on drunk driving charges, cops said.

Off-duty Sanitation worker John Paczynski, 34, was charged with third-degree assault after he socked another man in the face during a fight on a booze cruise at 23rd Street and the FDR Drive around 3:45 a.m., according to police.

The victim refused medical attention.

About an hour later, NYPD School crossing guard Aleshia Keane-Ottley, 39, was busted for punching a 28-year-old man in the face because he was standing too close to her — or someone she was with — on line at a McDonald’s on West 3rd Street near Sixth Avenue in Grennwich Village, cops said.

She was also charged with third degree assault, and her victim also refused medical attention.

And around 2:30 a.m. in Queens, NYPD police attendant Sandy Gibbs, 52, was arrested after he slammed his grey Nissan Pathfinder into several parked vehicles as he drove north on 113th Street.

When cops arrived, they found Gibbs sitting on the curb with watery eyes, slurred speech and alcohol on his breath. He was charged with driving while intoxicated.
