The mother of a 32-year-old man looked like she had come off worst in a boxing match after he attacked her at his Oswestry home, a court heard.
Liam Stewart launched the savage assault punching his mother up to 10 times and although she managed to escape he followed her and carried on the attack in the street.
A badly beaten Susan Stewart was covered in blood and had to crawl under a garden trampoline to take refuge from the onslaught before a neighbour intervened.
At Shrewsbury Crown Court last week Stewart was committed to hospital under the Mental Health Act and will only be released with the authority of the Secretary of State for Justice.
Judge Robin Onions said it was a “desperately sad” case and said he was satisfied Stewart, who has suffered mental health problems for many years, was a risk to the public and a danger to his mother in particular.
“Mrs Stewart looks like she has been in a boxing match and came off very much the worst,” said Judge Onions, who noted that her blood had been “literally sprayed” around Stewart's Swan Lane flat in Oswestry.
Judge Onions said it was pretty clear Mr Stewart was a normal lad until he was in his teens and his mother had done absolutely her best.
In a letter to the court Mrs Stewart said it was her view that her son had not been given the help his mental illness required.
Consultant psychiatrist, Professor Iqbal Singh, gave evidence to the court and said Stewart suffered from autism spectrum disorder and paranoid delusion disorder.
He said treatment at a specialist hospital in Harrow was available and could take up to two years.
Judge Onions said he “shuddered to think” what would have happened to Mrs Stewart had it not been for the action of neighbour Samantha Cobb who repeatedly tried to stop the attack despite being assaulted several times by Stewart herself.
Awarding Mrs Cobb a monetary reward of £250 for her bravery Judge Onions commended her actions and said the word brave “does not go halfway” to describe her actions, putting herself in harm’s way time after time until other neighbours were able to restrain Stewart.
Stewart had admitted inflicting grievous bodily harm on his mother on August 13 last year and assaulting Mrs Cobb, causing her actual bodily harm.
The offences happened while he was subject to a suspended prison sentence for attacking a neighbour with a hammer in August 2011.
Robert Edwards, prosecuting, said that during the onslaught Mrs Cobb tried to intervene and although she was punched several times by Stewart she was able to stop him getting to his mother.
At one point Mrs Cobb punched Stewart in a bid to shock him into halting the assault, but she was struck again by the defendant and went to the floor. He had his hand over her nose and mouth while using his other hand to repeatedly punch her.
When Stewart’s mother came out from below the trampoline, he punched her again, before other neighbours eventually rugby tackled Stewart and restrained him until police arrived.
Debra White, for Stewart, said his mother felt had been let down by the mental health services and Mrs Stewart had done all she could for her son.
“Clearly at a time when he was very unwell and needed support and help from those who have the ability, and experience, and the time to help him, unfortunately that did not happen,” she said.
