Former cage fighter Paul Allen admitted conspiracy to kidnap, rob and possess a firearm after the gang stole £53million from the depot in Vale Road in 2006.
The 40-year-old from Chatham was jailed for 18 years in 2009, and was told to repay £1.23million of the £1.9million that was supposed to have been his share from the raid.
He was released after six years; he also faced an extra five-year term added on to sentence if he failed to pay, but was not required to serve it.
A Freedom of Information request by the Evening Standard revealed the confiscation order ‘was handled in line with the relevant legislation’.
The Crown Prosecution Service said: “The CPS works hard to seize assets from criminals to stop them from benefiting from their crimes. In a small number of cases, a certificate of inadequacy can be offered when the sale of a person’s assets does not meet the original valuation.”
The depot manager Colin Dixon was kidnapped, along with his wife and seven-year-old son, and held at gunpoint so the gang could gain access.
Then 14 members of staff were tied up while the criminals loaded a 7.5-ton lorry with used notes during the 66-minute operation.
Allen fled to Morocco with Lee Murray, a fellow cage fighter who masterminded the raid.
They embarked on a lavish lifestyle but Allen was later arrested in the North African country and spent 20 months in prison before he was brought back to Britain to face trial.
He denied all knowledge of the robbery and jurors were unable to reach a verdict in the first trial at the Old Bailey. But he admitted charges of conspiracy to rob, kidnap and possess firearms before a retrial at Woolwich Crown Court.
Around £21million has been recovered by police with the remaining £32million believed to have been spent or be untraceable.
