The device, which thieves use to steal credit and debit card information was found late last week. This is the third device found at this same Mobil station in the last few months.
The North Port Police Department was working with the U.S. Department of Agriculture, when they found it during a routine inspection.
Other gas stations such as the RaceTrac the new Walmart gas station in North Port have stronger protection against these skimmers.
"Certain gas stations have it where if a machine is opened in any sense, the entire pump shuts down," says Josh Taylor, City of North Port spokesman.
Police do not believe any sensitive information was stolen from the skimmer.
