A police officer lied about a wrong-way, drunken-driving crash in which he wrecked a Porsche, Bronx prosecutors said yesterday.

Jackfen Lazarre, 34, pleaded not guilty in Bronx Supreme Court to charges of falsifying records and reckless driving.

Lazarre was driving north in the southbound lanes of the Major Deegan Expressway on Feb. 16, 2011. when he smashed the car.

After the accident, Lazarre claimed to fellow officers that he crashed after another car hit his Porsche from behind.

But his claim didn’t match with the evidence, authorities said — and they also say he was drunk when the crash occurred.

No one was injured in the accident.
