A violent patient seriously injured two members of staff at a mental health centre in a vicious knife attack, a court heard.

Myha Grant inflicted 17 wounds on health care assistant Julius Falomo and six wounds on nurse Francis Barrett.

The 31-year-old had been held at the Bracton Centre secure unit in Dartford after he smashed a champagne bottle over a man’s head in a random attack in Brixton, south London.

Victim Ali Awes was shown in CCTV footage lying unconscious on the ground after the attack on June 2 last year. He suffered a deep cut to his head, other wounds and he lost a tooth.

Grant was transferred to the Bracton Centre, run by Oxleas NHS Foundation, from prison on July 15. While there, he was agitated and singing offensive rap lyrics and talking about raping white women.

Two days after arriving at the centre, Grant pushed Mr Barrett aside and grabbed a knife being used to prepare lunch.

He then repeatedly stabbed Mr Barrett. Other staff members, including Mr Falomo went to his aid.

As Mr Falomo tried to restrain Grant, he was hurled to the floor and also stabbed repeatedly to his upper body.

As he carried out the attack, Grant was crying out “Allahu Akbar - Jah Rastafa”.

He then started a fire in the communal area, removed his bloodstained clothes and burnt them along with the knife.

Another staff member hid in one of the rooms which filled with black smoke. The windows were smashed and she was dragged to safety.

Prosecutor Simon Taylor said photographs showed “the general level of carnage” caused by Grant, who had written his street name Taz either in blood or tomato sauce next to his pile of burning clothes.

After his arrest, Grant told police staff had “dissed” him and he had sorted them out.

Mr Taylor said Mr Barrett’s injuries included wounds to his small bowel, chest and both arms.

Mr Falomo had wounds to his chest, abdomen, small bowel, groin, left shoulder and arm, left buttock, shin and right elbow. He needed four units of blood.

Mr Barrett was detained in hospital for 12 days. He has since suffered from nightmares and has not returned to work.

Father-of-four Mr Falomo was said to have been “rendered emotionally vulnerable in every aspect of his life” and become a social recluse.

Because he had not been able to return to work his basic salary was to be the subject of a downward review, which could result in it being reduced.

The victim of the Brixton attack suffered flashbacks and was scared to leave his home.

Judge Jeremy Carey said it seemed Mr Falomo’s actions were “extremely brave”. Both staff members suffered life-threatening injuries.

Grant, of Ellison Road, Streatham, south London, was originally accused of two offences of attempted murder, but his guilty pleas to wounding with intent were accepted.

He also admitted arson and wounding Mr Awes with intent.

His previous convictions include robbery, wounding with intent and grievous bodily harm.

Psychiatrists found that Grant, who appeared by video link with high security Broadmoor Hospital in Crowthorne, Berkshire, was suffering from a mental disorder and recommended that he be detained in hospital indefinitely.

Judge Carey adjourned until February 13, when he is expect to make a “hybrid order” which allows for an offender to be detained in hospital and if treatment is no longer necessary the remainder of the sentence would be served in prison.
