Columbus police are warning you to be cautious after a credit card skimming device was discovered inside a gas pump at a Columbus gas station.

Police were called Friday to the Circle K Gas Station, at 1644 Central Avenue, says Lt. Matt Harris, spokesman for the police department. The device was located after a contractor, who conducts routine checks and who noticed that a gas pump had been tampered with. A skimmer was found inside the pump.

Investigators believe that the device was placed in the pump between 12:00 p.m. April 6th and 12:00 p.m. on April 7th. If you used your credit card to purchase gas at the pump during that time, police are encouraging you to monitor your credit card statements and if necessary request a new card.
