NYPD Deputy Commissioner of Intelligence and Counterterrorism Rebecca Weiner joined “Mornings On 1” Thursday to discuss the department’s efforts to crack down on ghost guns after busting a ghost gun operation inside an East Harlem day care center this week.

The NYPD arrested three individuals Wednesday in connection with the operation, including 18-year-old Karon Coley, who was allegedly operating out of his mother's apartment, which is registered as a day care center on 117th Street.

Coley and two minors now face a slew of charges, including criminal possession of a loaded firearm and manufacturing a machine gun.

The case came just days after officials say a 1-year-old boy died from fentanyl exposure at a Bronx day care.

During the execution of search warrants, detectives uncovered a 3D printer, two completed printed firearms and an assault pistol, police say.

Weiner emphasized that the department will be continuing to educate the public on the new technology, so they can be aware of who may have access to assembling the “invisible” firearms, which lack traceable serial numbers.

“Many people wouldn't necessarily know what a 3D printer looks like, or that you can readily purchase one online along with the blueprints for creating these firearms,” she said.
