ONE of the men convicted of murdering soldier Lee Rigby has admitted to attacking a nurse in Broadmoor Hospital.

Michael Adebowale, 28, pleaded guilty to punching a healthcare assistant while being held in the secure hospital on July 20 last year.

After denying a more serious charge of inflicting grievous bodily harm, Adebowale admitted an alternative charge of assault causing actual bodily harm at Reading Crown Court today.

Adebowale was given an eight-month prison sentence by Mr Justice Jay which will be served after his 45-year minimum term for the murder of the soldier in Woolwich in 2013.

He is currently serving his sentence at Broadmoor in Crowthorne and is expected to stay there for the next few years to be treated for paranoid schizophrenia.

Mr Justice Jay said: "There is only one previous conviction but it is a significant one."

Adebowale and Michael Adebolajo ran over the 25-year-old soldier close to Woolwich barracks in May 2013 before stabbing him to death in broad daylight.

The father of one died as a result of multiple cut and stab wounds after the attack fuelled by Adebowale and Adebolajo's extremist beliefs described as a "betrayal of Islam" at their murder trial in 2014.

Adebowale has spent three periods in Broadmoor since his conviction, and is expected to spend the next "five or 10 years" in the hospital, the court heard.

Adebowale, who has changed his name by deed poll to Ismaail Kuti, appeared via video link from the secure hospital for the hearing.

Sarah Whitehouse QC, prosecuting, said that Adebowale punched the nurse in the jaw during the incident in a day room of the hospital.

Ms Whitehouse said the attack was triggered after Adebowale was asked to turn down the volume of a TV he was playing music through.

Adebowale was "plainly upset and annoyed" by the request, she added.

CCTV footage shown in court showed Adebowale approaching Jason Taplin before punching him and knocking him to the ground.

Mr Taplin was taken to hospital and examined.

After it was disputed whether the injury had broken the bone, Adebowale was able to plead guilty to the lesser charge and avoid a trial.

Sasha Wass QC, mitigating, told the court Adebowale admitted hitting Mr Taplin when frustrated but did not break the bone.

She said: "He accepted that he struck a blow, one blow, but he did not or he would not accept that he broke the jaw."

Ms Wass added that Adebowale suffers from "chronic paranoid schizophrenia" and was hearing voices telling him to attack Mr Taplin before the incident.

She said: "He is clearly unwell, he clearly had a lapse in self control and he regained his self control and he immediately showed his remorse by writing a letter to Mr Taplin.

"His medication was not sufficient to deal with the psychotic state he experienced on July 20 of last year and as a result of that state he administered the blow."

After serving his life sentence, Adebowale will serve half of the eight-month prison sentence before being released on licence.
