Bartholomew County deputies are warning of a robbery that happened after a meetup to buy a cell phone, arranged through Facebook.

The incident happened at almost 11 p.m. Monday night in the 8700 block of Old Nashville Road, says Judy Jackson, spokeswoman for the sheriff’s department. The would-be buyer met the seller of the cell phone through Facebook and then drove the seller to what he was told was the seller’s home.

Instead, the passenger pointed an object from his jacket pocket and demanded the victim’s cell phone and wallet and then ran away, Jackson says.

Deputies, including the department’s police dog Diesel, searched the area but couldn’t find the suspect.

Sheriff Matthew A. Myers warns that if you are buying or selling to someone you met online, you should ask specific questions that only someone who owns the product would know.

“If they can’t answer basic questions, there is a good chance they don’t actually have the product and chances are it is a setup to rob you,” Myers said.

He also cautioned to always meet in a public place, never got to a secondary location and if it sounds too good to be true, it probably is.
