Collins (pictured outside Westminster Magistrates' Court) has been sent back to prison after failing to pay back money gained in the Hatton Garden heist of 2015
One of the 'diamond wheezers' behind the infamous Hatton Garden jewellery heist was sent back to prison today after refusing to hand back his share of the haul.
John Collins was jailed for more than three years at a confiscation hearing relating to the tens of millions of pounds of jewellery and cash stolen from an underground vault in central London over Easter in 2015.
The 78-year-old - known as 'Kenny' - and two other elderly ringleaders were jailed for seven years after admitting conspiracy to burgle the north London vault the following March.
He, along with heist mastermind Brian Reader, 80, and fellow ringleaders John 'Kenny' Collins, 78, Daniel Jones, 64, and Terry Perkins, who died in prison last year aged 69, were hit with one of the biggest confiscation orders in Scotland Yard's history.
Collins, who appeared in the dock wearing a blue shirt and blue jeans, nodded to family members who shouted 'Stay strong, Kenny! and 'We love you, Kenny' as he was sent down for not handing back £7.5 million.
The OAP answered 'I can't hear you' when asked to confirm his name, address and date of birth to the court.
Jailing him for failing to raise a default sum of £7,502,519.60, District Judge Richard Blake said: 'I recognise Mr Collins is in his 70s.'
But he added: 'It was entirely his decision to commit this crime at a time of life when most people enjoy a quiet retirement.

'The consequences of this crime is very significant loss amounting in many millions in property of the victims. It's important that perpetrators of crime do not profit from their conduct.
'I'm satisfied that Mr Collins has wilfully refused and culpably neglected in the realisation in these assets.'
He said a joint confiscation order of £13.69 million was made against the gang which was deemed available in 'cash, jewellery, precious metals and other items'.

This included more than £7 million of 'unrecovered proceeds' of the burglary. Collins has been ordered to pay back a total of £7.6 million, including the proceeds of his share of a house in Islington, north London, and property in Spain, or face another seven years in jail.
His lawyer David Wood told a previous court hearing that he had handed over £732,000 and had been made a recent offer of £742,000 for his London home.
But today the District Judge said Collins 'despite ample opportunity, has failed to raise two significant assets - the London and Spanish properties.'

He added: 'I'm satisfied that his failure to realise the sale of these properties was willful refusal and culpable negligence.
'I'm further satisfied that there's been willful refusal and culpable negligence with regard to the hidden assets.'
He was jailed for 2,309 days, but was entitled to a statutory half reduction - making the jail term three years and four weeks.
Hendon Magistrates Court last month heard police had auctioned off some of the recovered stolen jewellery, which could not be returned to its owners, raising £110,000.
Collins, who is said to suffer from high blood pressure, has a £175,000 flat on the Costa del Sol in Spain that was taken over by
