Police have warned that a card skimmer who has stolen more than $70,000 from the bank accounts of Canberra victims could return.
Skimming devices were discovered at ATMs across the city in November last year.
Suspected ATM card skimmer caught on camera
ACT Policing have released CCTV footage of a man suspected of card skimming.
The devices extract card data from the magnetic strip of bank cards, while a tiny video camera records the victims keying in their PIN.
They have now been used to strip $70,000 from the bank accounts of Canberrans.
A key suspect was identified through CCTV footage in December, and police waited until Tuesday to go public with the images for operational reasons.
The clear CCTV image shows a man who has also been identified by NSW Police, and is suspected of committing similar crimes in that state.
Detective Acting Sergeant Rachel Batterham said the suspect seemed to have gone to ground.
''We can't say for certain whether this male is responsible for attaching the skimming devices, but he is responsible for unauthorised transactions from card-holders' accounts,'' she said.
''He's used a different card for each individual person's account, and he's gone to various ATMs, not the ones that were skimmed, and used those ATMs to withdraw money directly from a victim's account.''
Authorities fear the card skimmer may strike again, once he believes the scrutiny on local ATMs has cooled off.
Detective Batterham said the crime was ''cyclical'' in nature, and warned that Canberrans should not be complacent.
Police are urging ATM users to take extra precautions when using the machines, and to examine them for any irregular or unusual devices.
