Canberra residents are being urged to check their bank statements for unauthorised transactions after two illegal skimming devices were found attached to local ATMs.
Several ACT residents have contacted the ABC complaining that money was taken after they used either an electronic teller machine at Rudd Street in Civic, or one at Mawson in the past month.
Criminals use skimming devices to collect information from the magnetic strip on the back of ATM cards and steal funds.
In Europe the devices have become increasing sophisticated and include a miniature camera to record pin numbers.
Both illegal skimmers have now been removed and police are investigating.
Banks and credit unions are warning customers to avoid using ATMs which appear damaged, or have loose components or devices attached, and to inform staff immediately if they notice something suspicious.
