The Steamboat Springs Police Department is warning residents to be on the look out at gas stations in the area, after several reports of fraud have been linked to pay-at-the-pump gas purchases. Police were called to the Conoco on South Lincoln Avenue earlier this week, after an employee witnessed three men removing a suspicious item, that could have been a skimming device, from one of the pumps. Skimming devices read the information stored on the magnetic strip of a credit card, saving it to be used later, often in criminal activities. After transactions from the pump were checked, there was no indication of suspicious activity, but anyone who purchased fuel at the gas station is encouraged to check their bank statements. In a separate incident earlier this week, a customer received a fraud alert from their bank after 3 suspicious transactions were made, following the purchase of gas from a pump at the Southside Station on Weiss Drive. Card holders should be aware that their personal information can be acquired through skimming. The most effective way to guard against this type of fraud is to take advantage of your banks early warning fraud alerts, and to closely monitor your bank account activity.
