A FRENZIED killer who left his neighbour dying in a pool of blood after a brutal attack was today jailed for nine years.

Ernest Barrie attacked defenceless Alan Hughes with a knife, a metal pole, a walking stick and a toilet cistern lid in a sickening display of violence.

Mr Hughes, 38, suffered 47 injuries in the brutal attack, which lasted for 15 minutes, in July 2007.

Barrie, 54, was also ordered to be supervised in the community for three years after his release because of the risk he poses to the public.

He was originally charged with murdering Mr Hughes but the Crown accepted his plea of guilty to the reduced charge of culpable homicide on the grounds of diminished responsibility.

Sentencing Barrie at the High Court in Glasgow, judge Lord Matthews told him: "This is a very serious crime and a lengthy custodial sentence is the only possible sentence.

"I also have to make sure the public is protected from you after you are released."

The court heard Mr Hughes' downstairs neighbour became alarmed when he heard crashing and banging for 15 minutes and phoned the concierge.

James Wolffe, prosecuting, said police were called and arrived at the high rise block in Caledonia Road, Glasgow, at 8.25pm.

Mr Wolffe added: "They found Mr Hughes lying in a pool of blood. He died at the scene."

Mr Hughes was stabbed in the abdomen and groin and suffered other injuries.

Six psychiatrics examined Barrie and four of them concluded that he carried out the killing while suffering from a psychotic illness.

Barrie had been jailed for 18 years in 1986 for a £40,000 bank robbery in Blantyre, Lanarkshire, but was freed in 1989 after his conviction was quashed.

It followed an investigation by BBC's Rough Justice programme, which argued it was a case of mistaken identity and the wrong man had been convicted.
