A Slidell teenager who allegedly stole a cellphone made the mistake of then trying to sell it online, according to police.

A man reported Saturday that he had left his cellphone on top of a drink cooler while scanning items at a self-checkout register at Wal-Mart at 39142 Natchez Drive, according to the Slidell Police Department. The man told police that when he turned his back, the phone was gone.

Deciding to buy a new phone, the man was browsing Craigslist later that night when he saw his stolen phone listed for sale, police said. The man contacted Slidell police, who contacted the phone number listed on the ad. The number led them to 18-year-old India Carmouche, police said.

Carmouche agreed to meet with the undercover officer at a local restaurant to sell him the phone, police said. When the officer placed her under arrest, Carmouche tried to flee from the officer, but was apprehended.

“We quite frequently warn legitimate buyers and sellers about the dangers of Craigslist, but rarely do we issue a warning to criminals. So let this be a warning to all the criminals out there. You may also become a ‘victim’ on Craigslist when trying to sell stolen property,” Slidell Police Chief Randy Smith said in a news release. “Slidell is not the place to conduct illegal Craigslist transactions.”

Carmouche was charged with possession of stolen property and resisting an officer.
