A box truck driver who had no license plate was arrested in the hit-and-run death of an off-duty NYPD cop riding his motorcycle home from work, cops said. 

Carlos Almanzar Toribio, 30, was arrested hours after the fiery crash that threw the cop from his bike on the westbound Brooklyn-Queens Expressway near Atlantic around 8:30 a.m., authorities said. 

Detectives reviewed video from the scene that helped them identify the box truck, and Toribio was cuffed around 7:30 p.m., police said. 

The Washington Heights resident, who has no prior arrests, was charged with leaving the scene of an accident resulting in death, operating an unregistered vehicle and driving without a license plate, police said.

The 30-year-old officer – assigned to the midnight tour at the 84th Precinct in downtown Brooklyn – was riding a Yamaha R1 motorcycle on the westbound expressway when he was struck around 8:30 a.m. near Exit 27, authorities and sources said. 

Footage obtained by the Post shows the cyclist in the moments before the crash, whizzing along the expressway in the outermost lanes in the direction of the Verrazzano-Narrows Bridge.

The box truck driver fled the scene, and it’s possible he may not have even known he’d hit someone, the sources said at the time. 

Footage posted on X by Williamsburg News shows the cop lying lifeless on the road as his motorcycle went up in flames feet away.

The officer – who had not officially been identified by the department by Thursday – was taken to NYU Langone Brooklyn Hospital, where he succumbed to his injuries. 

His name was not officially released pending family notification. Online records show he joined the NYPD in February of 2021.
