Seven people, including convicted fraudsters, drug traffickers and money launderers were arrested in the Met's dawn raids this morning.
Officers targeted properties in Islington, Bromley, Southwark, Uxbridge, Hertfordshire and Essex, after warrants were issued by the courts for the non-payment of confiscation orders totaling over £2.6m.
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."
Convicted criminals, who have failed to pay back cash made from illegal activity, received an early wake up call from police this morning.
Metropolitan Police officers swooped on addresses across London, to enforce confiscation orders worth £2.6m.
Last year judges made a total of 6,269 confiscation orders, targeting the assets acquired by criminals through their illegal dealings. But, despite repeated court demands, millions of pounds have not been paid up.
