One of Lee Rigby’s killers is set to cost taxpayers £250,000 per year after justice chiefs agreed to transfer him back to Broadmoor Hospital.
Michael Adebowale, 25, was jailed for life for killing the soldier in Woolwich in May 2013, and was initially sent to Broadmoor before being sent to HMP Wakefield in 2015 when he was ruled to be sane.
But it is understood he has now returned to the high security psychiatric hospital in Berkshire after refusing to comply with medical treatment at the prison.
The cost of treating a patient at Broadmoor is around five times as much as the £50,000 spent on keeping a prisoner at a Category A jail.
According to the Sun, Mr Rigby’s mother Lyn, 50, is furious at the move after previously describing herself as ‘delighted’ when the killer was transferred to Wakefield.
She told the paper: ‘I get the impression this whole situation is going to yo-yo back and forth for years because the authorities clearly don’t know how to deal with him.
‘I need to be reassured that the right punishment is being handed down to the man who took my son’s life.
‘I can’t live with the thought he is slipping through a loophole to get out of proper jail time for what he did to my boy.’
Broadmoor is said to have ‘gentler surroundings’ than a prison and has been described as an ‘easier life’ for offenders.
Adebowale was jailed alongside Michael Adebolajo, 32, for murdering Mr Rigby with a meat cleaver and knives near the Royal Artillery Barracks in Woolwich, south east London, in May 2013.
They knocked Mr Rigby down in a car as he walked towards the barracks and then hacked him to death.
Adebolajo was given a whole life order for the crime while Adebowale was ordered to serve at least 45 years.
Adebolajo has previously complained about being segregated from other Muslim prisoners.
He was moved from HMP Belmarsh in Thamesmead, south east London, to Frankland in County Durham over fears that he was trying to radicalise other inmates.
Adebolajo and Adebowale were raised as Christians but later described as British Muslim converts at their trial.
Adebowale had openly discussed murdering a soldier on Facebook, but that information had not been passed to the intelligence services.
Adebolajo issued a series of threats to the West after the bloody murder took place.
A shocking video of him was taken on a mobile phone while he ranted with a machete in his hand.
