Baltimore County police say a 27-year-old Pennsylvania woman who used the online classified site Craigslist to arrange the sale of an iPad mini in Towson on Monday ultimately went home empty handed — without the iPad and without any money for its sale, as the potential buyer snatched the device and ran.

According to a summary of the police report, the woman met a man at 7:10 p.m., Nov. 12, in the 800 block of Dulaney Valley Road — near both the Dulaney Plaza Shopping Center and Towson Town Center mall — to sell a white iPad mini.

Police said the man tried to pay with counterfeit money, and as the woman reached for a pen to mark the bills and check their authenticity, he grabbed the iPad and ran north on Dulaney Valley Road.

Baltimore County Police Spokeswoman Cpl. Cathy Batton advised residents to remember that if you don't know who you're meeting when conducting transactions such as this, you can't be sure if they're being truthful in what a person selling or whether that person has any intention of paying for it.

Batton urged residents to have money transmitted through bank accounts and to deliver the goods by mail.

"If you are going to arrange to meet, make sure you do it in a well-lit space," she said. "Make sure there are plenty of people around you, and always make sure someone knows where you're going to be and what you're going to be doing. If at any point during your transaction you start to get the feeling something isn't right, listen to your instinct and leave."
