NYPD cop charged with stealing, selling guns from work An NYPD officer has been arrested for allegedly stealing guns from his precinct and selling them on the street, authorities said. Nicholas Mina was arrested late Thursday and charged with conspiracy, grand larceny and sale of a firearm, among other crimes. Information on an attorney wasn't immediately available. He and four co-conspirators who were also arrested are expected to be arraigned later Friday. The 31-year-old officer allegedly stole four guns from his colleagues' lockers and sold them to street buyers, sources familiar with the investigation told the New York Post. Read the original report at NBCNewYork.com Law enforcement sources said one of the buyers was an undercover officer. A six-year veteran of the force, Mina was part of a 24-hour security detail and had been assigned to guard the lockers after a series of thefts that included bulletproof vests, cash, and an iPad along with the guns, the Post reported. Mina allegedly sneaked one weapon out of the tightly watched locker room on April 22, after which a sergeant was assigned to watch the lockers, according to the paper. Police also put in a security camera to monitor the entrance to the locker room and installed an additional lock on each locker. Mina was arrested following an investigation by the NYPD Firearms Suppression Unit, Internal Affairs Bureau and Manhattan District Attorney's office. The alleged co-conspirators expected to be charged Friday include the alleged ringleader of the gun-buying scheme and a 38-year-old Internet mogul.
