The NYPD has shut down an elaborate gun-running ring that funneled more than six dozen firearms into the city from New Jersey and other “Iron Pipeline” states over the last year, officials announced Monday.

The weapons trafficking scheme was discovered during an undercover sting operation and involved at least six individuals, including a New Jersey-based ringleader and his Department of Corrections-employed girlfriend.

Authorities said it stretched from New York to Georgia and dated back to March 2015.

“Illegal firearms like these fuel the very violence in our streets we seek to combat,” Police Commissioner Bill Bratton explained Monday. “This is great takedown for us because it stops what’s going on.”

According to officials, 52-year-old Abdul Davis spent the last 13 months fetching guns from four different sellers in Georgia and Virginia. He was busted after he allegedly sold 82 of the

brand new firearms — including 67 pistols, 8 revolvers, 5 assault weapons, and 2 shotguns, as well as ammunition — to an undercover NYPD detective in Washington Heights.

There were 26 separate transactions over the course of the investigation — all of which took place in the vicinity of West 166th Street and Saint Nicholas Avenue, officials said.

Davis’ girlfriend, Shelita Funderberk, 50, also accompanied him on several of the sales trips, despite being a senior payroll clerk at East Jersey State Prison.

“We have her present during certain gun buys. She’s an active participant,” NYPD Chief of Detectives Robert Boyce said Monday.

A NJ DOC spokesperson later confirmed that Funderberk is an active DOC employee who was hired in October. In light of the charges against her, they declined to comment on her current status.

In addition to the lovebirds, the four Virginia and Georgia-based arms dealers who were charged on Monday included Trenton Pointer, 45; Daemon Jenkins, 49; Malik Rainey, 44; and Milton Tillery, 37.

They all face conspiracy and various criminal sale of firearms charges.
