Ketamine dealer Alexander Surin has been ordered to surrender a fleet of luxury cars including a Ferrari, Rolls Royce and £500,000 (£773,000) Bugatti Veyron, as well as a £2m London property empire.
Surin and his wife Jasbinder Boparan reached an agreement with the National Crime Agency (NCA) after a five-and-a-half-year civil recovery investigation that was started by the now-defunct Serious Organised Crime Agency.
In total, money, cars and property worth £4.5m will be handed to the NCA as part of a Civil Recovery Order made at the High Court earlier in February.
Surin - formerly known as Michael Boparan - has been deprived of his multimillion-pound assets since the investigation was started under a Property Freezing Order.
The NCA argued the assets were the result of money laundering, mortgage fraud, tax evasion and the importation into Europe and the UK of multiple tonnes of ketamine.
During their investigation, officers discovered £800,000 in the back of Surin's Rolls Royce Phantom.
While Surin, who is reportedly living as a fugitive in Dubai, did not agree with the agency's case, he and his wife chose not to contest the evidence at trial.
Surin has previously been arrested in relation to various criminal investigations, and was jailed in 2006 for fraud, but this is the first time his property has been subject to this level of asset recovery. The three London properties already sold totalled more than £2m.
Donald Toon, NCA director of Economic Crime, said: "The denial to Mr Surin of his extensive assets demonstrates the determination of the National Crime Agency to take every opportunity to disrupt serious criminality."
Civil recovery allows the NCA and the main prosecution agencies to sue for the proceeds of crime in the High Court. It is not dependent on a criminal conviction as the action is taken against the property and not against an individual. Cases are assessed on the balance of probability that assets have been acquired by criminal activity.
