Indiana State Police are warning you to be on the look out when you purchase gas. That’s after a credit card skimmer was found on a gas pump along Interstate 65 in southern Indiana.

Sgt. Jerry Goodin, spokesman for the Sellersburg State Police post, says that troopers were called to the fuel Mart Truck Stop in Austin on I-65 earlier this week after workers found the device. Nobody knows how long it was actually there, but state police say it could have been more than a week.

If you think your credit or debit card may have been compromised, you should contact the State Police post at 812-246-5424 or 1-800-872-6743.
