Victoria police has identified an emerging trend of fraudulent transaction using EFTPOS terminals, Victoria Police say.
The identified incidents are occurring when two or more offenders enter a business and purchase goods via a hand held EFTPOS terminal.
When entering a PIN, another offender will distract the employee as they amend the transaction to reflect they have been over charged.
When presented will a receipt they then demand a refund in cash.
Similar incidents have been identified where the offender will simply amend the transaction to become a refund.
In this instance the funds will be credited to their card instead of debited.
The offences have occurred mainly at food shops, but also other business such as clothing shops, florists and toy shops.
Incidents of this nature have been identified in the Melbourne CBD, Docklands, Chadstone, Sunbury, Fitzroy and Carlton, as well as regional areas such as Warragul.
Detectives from Yarra CIU have released CCTV images of three men following an incident at a restaurant in Fitzroy North.
On this occasion the offenders attend the St Georges Road restaurant they paid using a stolen credit card and amended the transaction to reflect they were over charged.
They then obtained a refund on a different cad.
The images depict three men investigators believe can assist with their enquiries.
Anyone who recognises the man or with information is urged to contact Crime Stoppers.
