Michael Seed was sentenced to ten years’ imprisonment in March 2019 after being found guilty of conspiracy to burgle, and conspiracy to conceal the proceeds.
He was found to have obtained a portion of the proceeds of the burglary of safe deposit boxes at Hatton Garden over the Easter Bank Holiday in 2015, with a calculated value of around £13.9m.
Following his conviction, Seed was made the subject of a confiscation order under the Proceeds of Crime Act (POCA).
A judgment handed down at Woolwich Crown Court on 1 October ruled that Seed must now pay back £5,997,684.93 within the next three months, or serve another seven years in jail.
Detective chief inspector Mark Bedford, of the Met’s Flying Squad, said: “The conviction and sentencing of Seed – more widely known as Basil – brought to a close one of the longest investigations in the Flying Squad’s history.
“He was responsible for accessing the Hatton Garden premises and disabling its security systems. He was the only outstanding suspect in the case until March last year when he was convicted.”
He added: “To date we have recovered just over a third of the property stolen from Hatton Garden, and much of it has already been returned to the victims.
“We have always said that the end of the trials for those involved did not mark the end of this investigation. Over many years specialist financial investigators have been working hard to locate outstanding property and identify the assets of these defendants.”
It comes as Proceeds of Crime orders have already been served against the other gang members, with the Met now achieving a further Order against Seed.
Bedford added: “Crime must not pay, and this should demonstrate the lengths we will go to ensure criminals are prevented from enjoying any financial benefit from criminality.”
