VANCOUVER, Wash. -- A device used by thieves to intercept credit card information was found Monday on a gas station pump in Vancouver, police said.

Vancouver police said the skimming device had been plugged into the wiring behind the panel of a gas pump at the 7-Eleven at 5600 E. Fourth Plain Blvd. It didn't impact customers' ability to purchase gas and it was well hidden from view, according to officers.

An employee servicing the gas pump Monday afternoon discovered the device. It's unknown how long the device was on the pump and, at this point, it's unclear if information was downloaded by those who placed it at the pump.

Police seized the skimming device as evidence and the department's digital evidence crime unit will examine it.

No skimming devices were found on the other pumps at the gas station.

Anyone who used the pump over the past few months at the gas station should check their credit statements for unauthorized charges, according to police.

Vancouver police said skimmer devices have become more common at gas stations, banks and retailers. Officers said merchants should be diligent in the maintenance of their credit card machines.
