Johnston and Wake county authorities are jointly investigating a rash of credit card skimmers found at convenience stores in both counties in recent weeks.
Some of the more recent skimmers were found on credit card swipe machines inside stores in the Clayton and Garner areas. One of the skimming devices was found at the Sheetz on Highway 50 at Highway 42.
Previously the skimming devices had been found only at credit card swipe machines at fuel pumps outside the businesses.
Federal authorities are also assisting with the investigation.
