Outsourcing company G4S has paid £24m to the government after admitting overcharging for electronic tags.
G4S even charged the government to electronically tag dead people.
The company now says that its old billing practices were "not consistent with the contract or G4S' values".
A government audit also found that G4S charged the government to tag offenders who were back in prison. Or were abroad.
(It's only a couple of years since two G4S employees electronically tagged an offender's false leg.)
They were sacked after tagging criminal Christopher Lowcock on the wrong leg. He would simply remove the limb and go about his normal business.
This follows last year's chaos when G4S won the contract to supply security staff for the London Olympics.
The company's floppy-haired boss Nick Buckles resigned following that chaos.
But probably the worst thing that G4S have produced is this company song.
It's called "Securing Your World". After the Olympics fiasco they attempted to scrub it from the internet.
