A KILLER left his neighbour dying in a pool of blood after a frenzied 15-minute attack.

Ernest Barrie, who had a bank robbery conviction overturned after a TV show investigation, attacked defenceless 38-year-old Alan Hughes with a knife, a toilet cistern lid, a walking stick and a metal pole.

The High Court in Glasgow heard that Mr Hughes suffered 47 injuries in the assault.

Mr Hughes' downstairs neighbour became alarmed when he heard crashing and banging which went on for about 15 minutes and telephoned the concierge.

James Wolffe, prosecuting, said when police arrived at the high rise block at 305 Caledonia Road, Gorbals, Glasgow, they found Mr Hughes in a "pool of blood".

Mr Wolffe added: "At that stage he was conscious, but his condition deteriorated. He died at the scene."

Barrie, 54, admitted the culpable homicide of neighbour Mr Hughes in his home on July 26, last year.

Barrie was charged with murder, but the Crown accepted his plea to the reduced charge on the grounds of diminished responsibility.

Mr Hughes' injuries included stab wounds to the abdomen and groin. Mr Wolffe said: "The cause of death was loss of blood."

Six psychiatrists examined Barrie and four concluded he carried out the killing while suffering from a psychotic illness.

Judge Lord Matthews deferred sentence on Barrie, who is detained at the State Hospital, Carstairs, until later this month for reports. Solicitor advocate Des Finnieston will give his plea in mitigation then.

Barrie was freed from an 18-year jail term in 1989 after his conviction for bank robbery was quashed.

This followed an investigation by BBC's Rough Justice which argued it was a case of mistaken identity.

Barrie was jailed in 1986 after being convicted using unclear CCTV images of a £40,000 raid on the Clydesdale Bank in Blantyre, Lanarkshire.
