Triple child murderer Axel Rudakubana allegedly left a prison officer in hospital after pouring boiling water over him.

Rudakubana, sentenced to 52 years behind bars at HMP Belmarsh in London, launched a pre-planned attack on the guard.

The 18-year-old allegedly launched the scalding liquid at the officer through a hatch in his cell door.

GB News can confirm that the convicted murderer is now being investigated over the alleged assault.

London's Metropolitan Police is now investigating the incident. Scotland Yard said: "The Met is investigating after a prison officer was subject to a serious assault at HMP Belmarsh on the afternoon of Thursday, May 8."

One source told The Sun: "This is terrifying and shocking in equal measure - and questions will be raised about this attack, especially coming so soon after the one by [Manchester Arena bomber's brother Hashem] Abedi.

"One of those will be why Rudakubana had access to boiling or hot water, and how on earth he was able to carry this out."

The source added that other prison guards heard the officer screaming before terror-obsessed Rudakubana was restrained.

A Prison Service spokesman said: "Police are investigating an attack on a prison officer at HMP Belmarsh yesterday.

"Violence in prison will not be tolerated and we will always push for the strongest possible punishment for attacks on our hardworking staff."

The officer "miraculously" only suffered minor injuries from the attack and is now expected to return to work next week.

It follows another vile attack on prison guards by Abedi at HMP Frankland in County Durham last month.

The Manchester Arena bomb plotter's "unprovoked attack" left staff with life-threatening injuries including burns, scalds and stab wounds.

He was later moved to Belmarsh - where he was unable to come into contact with the Southport killer.

The high-security facility in southeast London also made headlines at the start of 2025 when Sara Sharif's father Urfan was "sliced in the neck" with a jagged tuna tin lid.
