A Uniondale teenager was arrested over the weekend and charged with setting up an online scam claiming to sell cellphones, but instead robbing at least one victim, Nassau police said.

Nassau police said they arrested Jahmani R. Harleston, 17, of Nassau Road, on Saturday after a sting operation.

Police said they received a call Saturday from a 51-year-old woman who said she planned to buy a phone she saw advertised online from a man. The woman said she met up with the man, identified as Harleston, at a home on Sterling Street in Uniondale and paid $200 for the phone. But she said the man pushed her and ran away with the phone and her money, police said.

Later that day, the woman saw the same phone for sale online, and set up a meeting at a home on Searing Street in Hempstead, where she was joined by First Precinct police officers.

Harleston ran away when officers identified themselves, police said. They detained him a few moments later and charged with him with fourth-degree grand larceny and resisting arrest.

He was arraigned Sunday at First District Court in Hempstead and released to probation, according to online court records.
