An NYPD officer with Long Island roots faces a likely 15-1/2 year prison term at his sentencing on Nov. 7 after pleading guilty to stealing guns from his station house and selling them to support an oxycodone habit.

Nicholas Mina, 32, of Queens, who is listed with a voter registration address at his parents house in West Babylon, pleaded on Tuesday to conspiracy and gun and drug sale charges in Manhattan Supreme Court.

A 4-1/2 year NYPD veteran, he lifted the guns from the lockers of fellow officers at the 9th Precinct in Manhattan's East Village over a six-month period before his arrest in July. He faces 15-1/2 years as part of his plea bargain.

"As a New York City police officer Nicholas Mina had the duty to protect citizens, but instead, he put their lives, and the lives of his fellow officers, at risk," said Manhattan District Attorney Cy Vance.
