A "very dangerous" offender who repeatedly attacked a man, trashed a Bristol church and assaulted police has been jailed.
Martin Templeton, who has mental health difficulties which have proved to be untreatable, was responsible for a catalogue of offences spanning from late last year into this year, Bristol Crown Court heard.
The 34-year-old, of no fixed address, pleaded guilty to wounding Craig Hill on August 19 last year.
He pleaded guilty to causing £20,000 damage at Holy Trinity Church, in Kellaway Avenue, Horfield, on September 16 last year.
He also admitted causing actual bodily harm to and theft from Craig Hill in December 2 last year and assaults on three police officers on May 2 this year.
Judge Julian Lambert jailed him for five years and eight months.
He told Templeton: "You are responsible for a horrifying catalogue of offending.
"You know how much damage you can do. You are dangerous, very dangerous. You are often deluded. When you are ill you lack all self-control.
"You are simply not treatable, largely due to a failure to engage; when you kick off, you kick off big time."
Susan Cavender, prosecuting, said homeless Craig Hill had just been released from Bristol Royal Infirmary when Templeton struck him several times from the back in King Street, Bristol.
A bloody Mr Hill went to the Famous Royal Navy Volunteer pub and police found Templeton nearby, with a rusty chisel in his bag.
He made no comment and was bailed.
Around a month later Templeton caused £20,000 damage at Holy Trinity Church - from which he was previously given food - by smashing some 37 windows and lead window frames.
Police found Templeton on a nearby park bench, he made no comment and was bailed again.
Ms Cavender said Templeton tracked down Mr Hill and attacked him at his supported flat on December 2 last year.
The court heard he gained access to his victim by claiming he was a relative, and Mr Hill's mother had cancer.
Mr Hill was punched and kicked and had £200 worth of property stolen including two pairs of training shoes, medicine and bedding.
Templeton was arrested on December 24 and told police Mr Hill was unwell and mistaken, the court heard.
In a fourth incident, police arrested Templeton in an alley near Ebenezer Church, Filton Avenue, and said if he was refused a cigarette he would "kick off big time" and he may have Covid-19.
When police tried to place him in a car he headbutted one officer, spat in another's face and kicked a third.
In the melee Templeton screamed: "You all deserve to get Covid-19 anyway, you don't do your job!"
He told one constable: "I hope you get it, I hope you're on a ventilator for the next four months, you f-ing, filthy, pig prick."
James Haskell, defending, said was diagnosed with an autism spectrum disorder from the age of 15 and had experienced transient episodes of psychosis.
He told the court his client was released from a jail term last year into a chaotic lifestyle in which he was homeless and drinking excessively.
Mr Haskell said: "This offence undoubtedly coincides with a significant deterioration in his mental health."
