A convicted murderer has had four years added to his sentence after breaking a prison officer’s jaw.

Charlie White was previously jailed for life for killing a homeless man in Loose, near Maidstone in 2018.

Razvan Sirbu had been sleeping rough in the Loose Valley Conservation Area when he was attacked by White with a meat cleaver and his accomplice Alex Macdonald with a piece of wood.

A post-mortem found the Romanian man died from “blunt force trauma” to the head and body.

The judge had called the murder “a shameful, senseless act of mindless brutality” and jailed the pair for life.

White, 19 at the time, was ordered to serve a minimum of 16 years before being considered for parole, while Macdonald, also 19 at the time, was ordered to serve at least 18 years.

Now, White has had four years added to his tariff after breaking a prison officer’s jaw.

On September 23, 2022, White attacked a guard from behind while incarcerated at HMP Whitemoor, near March, Cambridgeshire.

White, now 25, threw a barrage of punches at the man that knocked him to the floor. As the victim attempted to get up White tried to knee him in the face.

Both men then fell to the floor and White began to wrap his arms around the victim’s neck, causing him to struggle to breathe.

Other officers arrived at the scene and it took several of them to loosen his grip around the victim’s throat.

The man was taken to hospital where he underwent surgery to have plates inserted into a broken jaw.

He also suffered nerve damage, as well as fractures to his cheekbone and eye socket.

The attack followed an incident on June 7, 2022, where the officer had conducted a routine search of White’s cell with a colleague.

During the search they found and confiscated an improvised weapon.

White denied assault causing grievous bodily harm with intent but admitted unauthorised possession of an offensive weapon in prison.

Yesterday (March 27) at Peterborough Crown Court he was found guilty of the assault charge and had his existing sentence increased.

DC Emma Purser said: “This was a cowardly unprovoked attack on someone who was just trying to do their job.

“The ferocity of the attack has left the victim with ongoing nerve damage and numbness.

“Fortunately, the other prison officers were quickly on scene and prevented him from suffering further injuries.

“Prison officers do an incredibly difficult job under what can be very challenging circumstances.

“They deserve to do this without being attacked.”
