Gun and dumber for con in Uber drug bust

A bungling career criminal left a handgun in the back of an Uber car — and then showed up to collect the weapon from an undercover cop while carrying heroin in his underwear, a police source said Sunday.

Henry Figueroa thought he could retrieve his loaded Smith & Wesson .380 — which he forgot in the car on Feb. 28 — by telling the driver he was a cop who had lost his service weapon.

According to court papers, he sent a text to the driver the morning after his ride saying that he’d forgot some “stuff ” in the back seat during the ride from the East Village to his Harlem apartment.

“I’m a police officer and I was wondering if I dropped my side arm,” he texted.

But the driver had already reported the handgun to cops, after seeing it on the back seat. At the behest of NYPD in- vestigators, the driver agreed to meet his former passenger and return the weapon.

But instead of the driver, an undercover officer headed to the meeting spot.

Figueroa, 28, was arrested — and when he was brought to the station house, officers discovered heroin in his pocket, prompting cops to do a strip search, the court papers state.

The cops then found a clear bag tucked inside his underwear, which contained 84 individually wrapped envelopes of heroin, the papers say.

Figueroa was booked on a charge of narcotics possession with intent to distribute, as well as a charge of felon in possession of a firearm.

His rap sheet includes marijuana possession, petit larceny and assault.
