Three British inmates who stabbed a convicted child killer to death inside a maximum-security prison were sentenced Friday to spend the rest of their lives behind bars.

Mark Fellows, 45, Lee Newell, 57, and David Taylor, 64 were seen storming the cell of convicted child killer Kyle Bevan, 33, at HMP Wakefield in northern England in November 2024, before walking out roughly four and a half minutes later, according to surveillance footage obtained by the BBC.

Bevan — serving a life sentence for the murder of his 2-year-old stepdaughter — was later found dead after suffering more than 25 stab and slash wounds.

At Leeds Crown Court on Friday, the trio received whole-life orders — the UK’s equivalent of life sentences with no chance of parole or release — for killing Bevan.

Judge Justice McGowan imposed new whole-life orders on Fellows and Newell despite both men already serving the punishment for previous murders.

McGowan said the three defendants were “congratulatory” after Bevan’s murder, and that word quickly spread through the prison that the child killer was dead.

“You chose him as your target as he had been convicted of the murder of a child,” the judge said, the BBC reported.

“Acting together, you wounded him more than 25 times; several of those wounds were fatal.”

“His last moments must have been terrifying,” she continued, according to the Daily Mail.

“It is certainly outside my experience to have ever had to sentence somebody for a third murder, and in two of these three defendants’ cases, that’s what’s just happened.”

Prosecutors said Bevan was ambushed inside his cell and repeatedly stabbed with makeshift weapons, including one fashioned from metal taken from the back of a television.

After the attack, his body was placed in bed to make it appear he was asleep.

The court heard Bevan bled to death in his cell before his body was discovered during a prison roll call the following morning.

Bevan was serving a life sentence for the murder of his partner’s 2-year-old daughter, Lola James, who died after suffering catastrophic injuries in 2020.

Taylor was also handed a whole-life order Friday for the murder of 24-year-old Alisha Apostoloff-Boyarin and the attempted murder of a police detective, in addition to Bevan’s killing.

Apostoloff-Boyarin disappeared after traveling from Manchester to Durham in January 2022.

Taylor pleaded guilty to murdering her earlier this year but has refused to reveal what happened to her body.

The court also heard that Taylor stabbed Greater Manchester police detective Darren Bratby during an interview at another prison after claiming he had information about Apostoloff-Boyarin’s disappearance.

The detective survived the attack and made a full recovery.

Fellows, known as “The Iceman,” was already serving a whole-life sentence for two gangland murders.

Newell was serving a whole-life sentence for murder and had previously been convicted of killing another child killer inside a prison cell in 2013.

There are believed to be only around 75 inmates serving whole-life orders in England and Wales, a punishment reserved for the country’s most serious offenders.
