NEW YORK (CBSNewYork) — A former NYPD cop has been sentenced to 15 and half years in prison for stealing police-issued firearms and selling them on the black market, the Manhattan District Attorney’s office announced Wednesday.

Nicholas Mina was also sentenced to five years of post-release supervision.

The 32-year-old pleaded guilty last month to criminal sale of a firearm, criminal sale of a controlled substance, grand larceny and other charges.

Mina admitted that he stole guns from fellow cops out of their lockers at the 9th Precinct on the Lower East Side and sold them on the black market in order to feed his prescription drug habit, prosecutors said.

He was arrested in July following an undercover investigation.

“This case is a striking example of the destruction that surrounds prescription drug abuse,” District Attorney Cy Vance said in a statement. “The defendant took an oath to protect New Yorkers from criminals. Instead, he worked alongside a gun trafficker in order to feed his drug addiction.”

Mina was a member of the NYPD for three years.
