A TSA screener at Newark Airport was recently busted in a major heroin den near her workplace — still wearing her spiffy, government-issued uniform, authorities said.

Samirah Saunders, 22, and two other women were collared in the March 6 raid at 86 Wainwright St. in Newark, just around the corner from an elementary school and a spot where cops found a load of ready-for-street-sale heroin, according to sources and court records.

Two other suspects, Gavin Barker, 23, and Mariyah Sanders, 20, were also arrested.

It wasn’t clear whether Saunders was still on duty or was going to or from work.

She’s accused of helping to distribute the 1,400 packets of heroin, stamped “Green Lantern” and “P Dope” in green ink, confiscated from the apartment, according to court records.

The fact that the pad was near a school resulted in Saunders’ being hit with an additional felony charge of possessing or distributing heroin within 1,000 feet of a school.

In her mug shot, a somber Saunders was still wearing her blue TSA uniform blouse, adorned with black epaulets.

Her lawyer, James Pomaco, insisted that his client went to the apartment just to say hello to the other women.

“She was at the wrong place at the wrong time,’’ he said.
