An 18-year-old driver of the reckless crew who doused an unsuspecting NYPD traffic enforcement agent with a fire extinguisher in a twisted prank has been arrested, police said.

Ammar Alhesheshi was behind the wheel of a gray sedan with three passengers when the car slowed down on Saint Nicholas Avenue near 118th Street as it approached a marked NYPD cruiser just before 7 a.m. last Thursday, cops said.

The front passenger yells “Yo!” at the 43-year-old traffic agent and unloads the fire extinguisher into the cruiser’s driver’s window, disturbing footage of the encounter shows.

The people in the sedan can be heard in the clip laughing and driving away as music plays in the background.

Alhesheshi was arrested in the Bronx Wednesday and charged with second degree assault, police sources said.

The curly-haired teen, dressed in a black T-shirt and jeans, kept his head down as he was led by cops out of the 28th Precinct in Harlem in handcuffs.

The agent suffered an eye injury during the attack. He was taken to Mount Sinai Morningside in stable condition for treatment, according to police.

Police have released images of two other suspects in the case.

Tattooed 19-year-old Escarlin Polanco Gonzalez, who has two prior arrests for reckless endangerment and robbery, is wanted by police, NYPD announced on Monday.

Local 1182, the union that represents 2,500 Big Apple traffic agents, has offered a $1000 to the public for any information that leads to arrest and conviction of Gonzalez, union Vice President Olufemi Sokunbi told The Post.

The NYPD also released photos of another unnamed suspect boarding an MTA bus.
