Folks at the Dollar General in Grafton say in the past few days, several men have come into the store attempting to buy large numbers of prepaid phones. However, store policy only allows a customer to buy two phones at a time, in fact, they are locked away from the general public.

The clerks say after they were in the Dollar General, the men went to the Grafton Walmart to try to purchase more of the phones.

Grafton police found one man during a traffic stop. They say he had hundreds of prepaid phones in his car.

There is no word on what the men planned to do with the phones or why they bought so many, but the incident was later turned over to the FBI for an investigation.

The owner of Country Roads Communications says the allure of the prepaid phones is the freedom that come with them. However, the FBI is not ready to say that the phones are being used for illegal or criminal purposes.

"Prepaids are hard to track, so they're used alot for illegal operations," said Vince Cafazza.

"We are aware that there are a number of purchases throughout the state. Large purchases of trac phones. We are interested in the purchases because they are unusual," said Dan Caldwell, FBI special agent. "We also understand that a number of the larger stores in the area are aware of the purchases. We are not aware of any criminal activity associated with the purchases at this point."

Caldwell says if you notice someone trying to buy large quantities of these type of phones, you can contact your local police or the FBI.
