Inmate tried to slash prison officer's throat at South Yorkshire jail chanting "Allahu Akbar"

Mukhtar Musse entered an office on K Wing of HMP Lindholme, near Doncaster, on April 22, 2019, and hit an alarm, saying: "Get my staff now," prosecutor Richard Sheldon said.

When he was confronted by two officers, Musse pulled out a makeshift blade and swung, just missing one officer's throat.

As he was being restrained he inflicted a seven cm neck wound just under the officer's chin, and a two cm cut under his left ear.

Both wounds were superficial and treated by tetanus injection, but because the knife was bloody, Musse's victim suffered "psychological harm" waiting for the results of a blood test.

Musse was restrained and taken to the segregation wing, still chanting, said Mr Sheldon.

On the way he tried to trip up the officers escorting him, lunged, and bit another officer on the knuckle, but he didn't break the skin.

On Friday, Sheffield Crown Court heard the Somalian national was sentenced to a minimum term of 30 years after his conviction for attempted murder and possession of a firearm with intent, in June 2008.

Psychiatrist Dr Ajay Pawar confirmed that he doesn't qualify to serve his sentence in a hospital.

Richard Thynne, mitigating, said: "He would not have committed these offences if he wasn't in the mental state he was."

Musse, 33, of HMP Doncaster, pleaded guilty to unlawful wounding, assault occasioning actual bodily harm and possessing a weapon in prison, after initially denying the offences, on October 6.

On Friday, Judge Rachael Harrison told him that he intended to cause more harm than he did, but deserved 20 per cent credit for his guilty pleas, entered two months before trial.

She said: "It was a planned assault on a vulnerable victim who had no choice but to tackle you."

She imposed an extended sentence of 36 months, comprising 24 months in custody and 12 months on licence. The parole board have control over his release

"These are concerning offences," the judge told Musse. "It is entirely necessary and relevant for the parole board to know. Your behaviour shows you present a significant risk to the public."
