Opening the panels did not disrupt service or trigger any alarms; and it only took seconds to install the skimming devices.

The devices were undetectable from the outside and were only noticeable when the panels were opened.

Detectives are notifying banks and their customers of the stolen credit card numbers and ask that gas station operators check all their equipment.

If a skimmer is found, operators are advised to not touch or remove the device, and contact local law enforcement.
