(Sidney, Iowa) – The Fremont County Sheriff’s Office said Thursday, credit/debit card skimmers were located on pumps 3,4, and 5 at the Casey’s Store in Hamburg, Thursday afternoon. Authorities said the skimmers have been on the pumps for an unknown period of time. Deputies are currently investigating the case and hope to have a timeline for the transactions where skimmers were used, as soon as possible.

The skimmers were placed inside of the fuel pump, on a circuit board which had been pried open. The sheriff’s office said the public would NOT have been able to locate the electronics without accessing the inside of the fuel pump.

Authorities say if you used pumps 3,4 or 5 at the Hamburg Casey’s Store recently, please check for any fraudulent activity in bank accounts, and if any fraudulent activity is observed, please call the Fremont Sheriffs Office to report it.
