A "DANGEROUS" man is today beginning an extended term behind bars after slashing a man's arms and hands with a knife.
Meow meow addict David Dickinson was told by Judge Paul Thomas that he had no choice but to pass an extended sentence on him.
He told Dickinson he will serve two-thirds of the six-and-a-half year and also have an extended licence period of three-and-a-half years upon his release.
Part of the reason the sentence was increased was because when he was 18, Dickinson had caused another man grievous bodily harm, again attacking him with a weapon and at the time of his latest offence, Dickinson was on licence from prison for dealing heroin.
Dickinson, now 26, from Constitution Hill in Swansea, had admitted causing Michael O'Brien grievous bodily harm after attacking him on his doorstep with a knife.
James Jenkins, prosecuting, said Mr O'Brien's injuries were not as serious as they could have been but only by "luck not judgement".
Paul Hobson, for Dickinson, said his client had "significant problems" with drugs but that when sober he had a genuine desire to do something about his addiction.
"When drug-free he is not a dangerous individual," said Mr Hobson.
The offence took place on Constitution Hill in Swansea in October last year.
Dickinson went to Mr O'Brien's home, in what the judge called a "premeditated" attack.
Dickinson was jealous over attention he believed Mr O'Brien was paying to his girlfriend and was paranoid because of his meow meow use.
As Mr O'Brien stood at his front door in the early hours, Dickinson used the knife to slash him to his arms and injuries were caused to his hand when he tried to protect himself.
Judge Thomas said: "It came out of the blue as far as he was concerned.
"In my view you are a dangerous offender and I consider there is a significant risk of the commission of further offences resulting in serious harm to others in the future.
"If you return to drugs you will remain a danger to others," he said.
