Hundreds of red light and speed camera fines are set to be refunded after an embarrassing technical glitch in Victoria.
A technician who plugged a USB into each camera's operating system unwittingly introduced a computer virus.
After radio station 3AW reported the cyber infection, police decided to waive all fines issued by the cameras from June 6 to June 22.
Fifty-five speeding and red light cameras were affected by the computer virus.
A total of 590 fines will now be withdrawn, including three that resulted in a loss of licence.
The camera locations included Alexandra Parade and Smith Street in Fitzroy North, St Kilda Road and Fitzroy Street in St Kilda, Dandenong Road and Warrigal Road in Malvern East, Mahoneys Road and High Street in Thomastown, and other locations across the greater Melbourne region.
"I cancelled the fines because I think it's important the public has confidence in the system,100 per cent confidence," police said.
