Make sure to alert the gas station operators if you see anything suspicious.

The Monroe County Sheriff's Office is warning residents about a credit card skimmer found at a gas station on Marketplace Drive in Henrietta. 

On June 22, a customer reported pump number 2 at Mobil Mart was not working.

Officers say the skimming device was found by a service technician on June 25.

Earlier this year, Messenger Post's news partner, News10NBC's Deanna Dewberry investigated how crooks easily access pumps and what gas station operators are doing to protect you. Here's Deanna's Do List:

Consider using a credit card at the pump rather than a debit card that's linked to your bank account. Choose a pump nearest the attendant. Thieves are more likely to put skimmers in the pump farthest away to avoid detection. Consider paying inside when paying with a credit or debit card. Use your Android phone to detect a Bluetooth signal coming from the pump. An app for Android phones called Skimmer Scanner detects a skimmer’s Bluetooth signal. The maker of the app is working on developing a similar one for iPhones. You can also check for skimmers by turning Bluetooth on in settings while standing in front of the pump. If your Bluetooth is trying to connect with a signal, be wary. The signal could be coming from the pump. If you see something, say something. Make sure to alert the gas station operators if you see anything suspicious.
