A jailed murderer who was killed by another inmate in the latest shocking prison security breach died of a head injury, police revealed today.
John Mansfield, who was jailed for life in 2007 for the drug-fuelled murder of his neighbour Ann Alfanso, 63, was attacked on Sunday inside HMP Whitemoor, Cambs.
Mansfield, who had 75 previous convictions, was murdered just a day after three prison officers were doused with boiling hot oil and stabbed with makeshift weapons.
In a separate attack on Saturday, Manchester Arena terrorist Hashem Abedi attacked three prison officers inside a separation centre in HMP Frankland, Co Durham.
In the latest incident, Mansfield, 63, was attacked by a fellow prisoner and died despite the efforts of prison staff.
A post-mortem has now concluded he died as a result of a head injury, Cambridgeshire Police said this morning.
A 44-year-old man has been arrested on suspicion of murder and remains in custody.
Police were called at 4.10pm on Sunday following the discovery of Mansfield’s body and he died at the prison at 4.27pm.

Mansfield, originally from Manchester, had been told he was unlikely to ever be released from prison following his 2014 attack on John Orme, a convicted rapist behind held at HMP Full Sutton, near York.
Then aged 52, Mansfield was said to have walked up to Orme in his cell and told him ‘I have a present for you’ before slashing him seven times with a broken plate in a row over a cooking pot.
The attack severed his victim’s artery leaving him requiring 22 stitches.
Mansfield received a second life sentence in 2014 for the attack.
It was the second time he had been convicted of a prison attack.
In 2011 he was convicted of wounding a man he hated with a chair leg inside Manchester’s Strangeways Prison.
Sentencing him to a second life term in 2014, Judge Jeremy Richardson QC, said: ‘This was a pre-planned and calculating attack on a fellow inmate. You would have carried on had you not been prevented.
‘I doubt very much it will ever be safe to release you. I have no doubt you are a very dangerous criminal who regards violence as the norm, who has no hesitation but to kill when necessary.
‘You killed an old lady. Now you have convictions for two violent offences in prison. I have every reason to believe it will never be safe to release you. You are a violent and very dangerous man who poses a considerable threat to the public.’

Mansfield claimed he could not remember stabbing his first victim when he was first captured.
Ann Alfanso was found dead in her home in May Road, Whalley Range, Manchester in 2006.
She had been stabbed about 20 times in the head and neck.
A post-mortem examination found she had a total of 97 wounds, bruises and cuts on her body as a result of the attack.
Mansfield admitted her murder which police believe he carried out for a ‘pocketful of change’.
Det Insp Steve Eckerlsey said at the time: ‘The murder of this woman was shocking enough in its violence and cowardice, but for her murderer to repeatedly state that he couldn’t even remember stabbing her almost 100 times is even more astonishing.
‘Ann was an easy target as she wasn’t able to move very quickly and had to have home help, as her neighbour Mansfield knew only too well.
‘He has admitted that he used to talk to Ann, and even do some shopping for her occasionally.
‘We will never know or understand what made him turn from a seemingly helpful neighbour into a savage killer that day.
‘It would appear the only thing Mansfield got out of murdering Ann was a pocketful of small change.
‘His actions that day were totally senseless and inhuman, but he knew exactly what he was doing.’
