An off-duty NYPD officer was busted early Tuesday for allegedly drawing a gun during a parking dispute with another man in Queens, cops said.

Aaron Cooper, 23, was arrested around 1:30 a.m. after a squabble with a stranger in front of the other man’s home on 154th Street, police said.

He allegedly called the victim “a slew of insults, causing him alarm,” a police spokeswoman said.

At one point, Cooper allegedly displayed a gun.

He was charged with criminal possession of a weapon, menacing, criminal mischief and harassment, cops said.

Cooper, who has been with the NYPD for one year, was suspended without pay, authorities said.
