Detective Superintendent Nick Downing, from the Met's Specialist and Economic Crime Unit said:
"Today is the start of our activity to ensure that those criminals who have had confiscation orders imposed on them by the court pay the outstanding amounts.
"We are committed to ensuring that asset confiscation acts as a deterrent and we will continue to target those with outstanding orders until the full amounts are paid.
"Our message is very clear: if you have an outstanding confiscation order, take every opportunity to pay it now.
"The enforcement of these confiscation orders matters to everyone, not just as a deterrent but also as a point of justice. For example, if people have been victims of crime and lost money, the judge, as part of the confiscation / forfeiture hearing, can instruct that a percentage of the money is paid in compensation to the victim."
