Two men stabbed a man to death over an alleged bungled drugs deal, a court has heard.

Warren Ricardo Blake, 18, and Tevin Birmingham, 21, were using a flat in Dickens Court, Great Yarmouth, as a drugs dealing base when they became involved in a confrontation with Andrew McGowan, a Norwich Crown Court jury heard on Wednesday.

Andrew Radcliffe, prosecuting, said that Mr McGowan, 33, who had taken a cocktail of drink and drugs, had gone to the address armed with a hammer in an attempt to either buy drugs or in a 'befuddled hope' of robbing Blake and Birmingham.

He said a confrontation in the bedroom ended with Mr McGowan being stabbed five times, with one fatal wound to his heart.

Blake, of Thorncliffe Road, London, and Birmingham of William Kett Close, Norwich, have both denied murder of Mr McGowan, on November 14 last year. They also deny the supply of cocaine on the same date.

Also in the dock are Charlene Barber, 34, of Dickens Avenue, Great Yarmouth, and Kevin Wood, 45, of Nelson Road Central, Yarmouth, who are alleged to have helped Blake and Birmingham, flee the scene after the fatal stabbing, by delaying calling 999.

They both deny doing an act to pervert the course of justice.

In his opening address to the jury, Mr Radcliffe said that there was a drugs background to the case.

Following the fatal stabbing, he said Blake and Birmingham were arrested in London, ten days later. He said Blake admitted stabbing the victim but said it was self-defence and Birmingham denied any involvement, although admitted he had been present.

The trial continues.
