Manhattan

He’s a bad seed.

A scam artist who posted Apple products for sale on Facebook ripped off his would-be customers after meeting with them at McDonald’s, Dunkin’ Donuts and other very public East Harlem sites, authorities said.

Terrell Anderson, 22, advertised that he could score Apple merchandise at steep discounts, court papers state.

At 3:30 p.m. on March 31, he met with a mark in the McDonald’s on Third Avenue near East 110th Street and was given $500 with which to purchase a MacBook laptop, cops said.

“Just wait for me out here — because it’s dangerous, and I don’t want you to get robbed,” Anderson ironically said before vanishing with the cash.

At 4:45 p.m. the same day, he met with two other victims at a nearby Dunkin’ Donuts and walked away with $800, purportedly for a MacBook and an iPhone, cops said.

Anderson was arrested Monday and charged with fraud and petit larceny.

Cops found a semiautomatic .40-caliber Glock hidden in a Graniteville home, after receiving a tip from the gun owner’s wife.

“A guy owed me money, and he gave me the gun for it,” David Coleman, 46, told officers searching his Arlington Place pad at 1 p.m. Thursday, according to court papers.

Coleman, who said he’d had the gun for three years, also kept 15 rounds of ammo and two magazines, cops said.

The gun was found to have been reported stolen in Dade County, Fla.

Coleman was charged with weapon and ammunition possession, according to a spokesman for DA Daniel Donovan.
