KEY LARGO (CBSMiami) – An investigation has been launched after credit/debit card skimmers were found attached to two bank ATMs in Key Largo.

Both ATM machines were at Bank of Americas, one at the 99 mile marker and one at the 92.2 mile marker. The skimmer devices were placed over top of the card slots on the machines.

The at mile marker 99 was found by a customer Sunday morning who put her card into the slot and it was not returned. The ATM machine’s screen gave a warning about the cards protection.

The customer subsequently discovered the skimmer device on top of the card slot – according to the report he said it appeared “flimsy” and he was able to just peel it off.

Monroe County Sheriff’s deputies checked other ATM machines in the area and discovered the second skimmer on the machine at the 92.2 mile marker.

Bank of America security and Sheriff’s detectives are reviewing their surveillance tapes to see if any customers’ cards may have been compromised. The bank reportedly checks their machines regularly to ensure they are not compromised and last checked these machines Friday.

The sheriff’s office said it is important to be alert to anything out of the ordinary when using your card. Skimmers have been found on ATM machines as well as inside gas pumps at various convenience stores in the Keys and elsewhere.

It is also very important to check the activity on your credit and debit cards frequently to catch any unusual or illegal activity that might be taking place as early as possible.
