The state's agriculture secretary says 15 credit card "skimming" devices have been found on gasoline pumps in different parts of the state in the past month.
The devices are used by thieves to steal credit card information from motorists.
Agriculture Secretary Mike Strain says the devices are becoming harder to detect. And some have Bluetooth capability; so, credit card data can be transmitted to the thieves without them having to approach the pumps and remove devices.
Strain's Tuesday news release says the 15 devices recently found contained about 4,000 credit and debit card numbers. They were found in Avoyelles, Calcasieu, Jefferson, Lafayette, Orleans, Rapides, St. Landry, St. Tammany and Washington parishes.
Strain is encouraging motorists who pay at the pump to closely monitor their credit and debit card charges.
