The Nassau County district attorney’s office charged an NYPD officer from Merrick on Thursday with drunken driving and other offenses stemming from an October 2015 Wantagh crash that seriously injured a passenger.

Gregory Lecrann, 29, faces charges of operating a motor vehicle while under the influence of alcohol, aggravated operating a motor vehicle under the influence of alcohol, aggravated vehicular assault, second-degree assault, first- and second-degree vehicular assault, second-degree reckless endangerment and reckless driving, authorities said.

An NYPD spokesman said Lecrann is still employed as a police officer on modified assignment performing administrative duties.

Lecrann, off-duty at the time of the crash, was arraigned before Acting Supreme Court Justice Jerald Carter on Thursday and pleaded not guilty to the charges.

Carter released Lecrann on his own recognizance.

Lecrann’s attorney, Kristin Galison of Mineola, did not respond to a request for comment. Lecrann is due back in court on July 21.

He faces 5 to 15 years in prison if convicted on the top charge.

Prosecutors said Lecrann and a passenger left a bar on Oct. 9, 2015, and got into a gray 2015 Nissan Altima.

With Lecrann behind the wheel, the Altima traveled on Sunrise Highway in Wantagh at 112 mph before striking a generator and utility pole in the center median, officials said.

The passenger was seriously injured in the crash and suffered a broken femur and scarring, officials said.

“We will prosecute this case aggressively because the conduct alleged here is outrageous, and put every driver and pedestrian in grave danger,” District Attorney Madeline Singas said in a statement.
