A prisoner on early release went on a knife rampage after a ‘legal high’ called Boomdust made him believe his home was being attacked.
Kyle Saville stabbed a large knife through a bedroom door and left two relatives terrified they were going to be attacked after he went berserk.
He became delusional and was convinced a gang was attacking the house in Barnstaple where he was staying with members of his family after being released from a jail sentence.
Saville, aged 21, had served half of a four year sentence for throwing a man off Ilfracombe pier and causing him serious injuries in 2011.
He was released and was staying at a house in Bevan Road, Barnstaple when he took the Boomdust and became delusional, Exeter Crown Court was told.
Saville admitted having a bladed article and criminal damage and was jailed for six months by Judge Phillip Wassall.
The sentence is unlikely to affect his release date because he has already been recalled to prison to serve the remaining two years of his original sentence.
The Judge also imposed a two year restraining order preventing him returning to the house in Barnstaple or contacting the two women who live there.
The judge told him:”You took a supposedly legal high called Boomdust and according to your own description it made you feel horrible. That does not surprise me.
“It had the effect of making you feel worried and jumpy and you became delusional and thought people with whom you were in conflict were trying to get into the house.
“You picked up a knife and in the belief you were protecting the house you began shouting irrationally and behaving in a dangerous way which ended in you putting the knife through a bedroom door.
“You may have had no intention of hurting anyone but you were completely out of it and the two women in the house were terrified. They did not realise what you were doing.”
Miss Bathsheba Cassel, prosecuting, said the unusual circumstances of the offence justified a restraining order which would put the minds of the two victims at rest.
Mr Nigel Wraith, defending, said Saville deserved credit for his guilty plea and had only armed himself because he was in a deluded state and believed he was protecting the property from intruders.
