A cagefighter from London who was part of a gang which carried out Britain's largest cash heist has been secretly let off paying back the fortune he helped to steal.

Paul Allen, who used to live in Chatham, received an 18 year prison sentence and was ordered to pay back £1.23 million after a violent raid on a Securitas depot in Tonbridge in 2006.

But, according to a Freedom of Information request by the London Evening Standard, he was let off the hook by a judge in closed court.

Allen was granted a 'certificate of inadequacy' to write off his debts despite initially being told he would face five years in prison if he failed to repay his ill-gotten gains by 2010.

He paid back only £420 and was excused from the five year sentence.

After the robbery, he enjoyed a lavish lifestyle of cocaine-fuelled parties, splashing out on luxury cars, and paying for breast enhancement surgery for his girlfriend after fleeing to Morocco.

He was later extradited back to Britain.

During the raid, the manger of the Securitas facility, his wife, and his child were threatened with death while 14 other members of staff were tied up and locked in cages for many hours.

For the robbery, Allen and his best friend teamed up with several others from Kent and a depot insider.

The gang disguised themselves as police officers, ambushing the manager before taking their £53m haul to a farm near Staplehurst in the back of a lorry.

Police recovered £21m but the rest vanished.
