THE jury heard that Pyke has served a prison sentence for causing grievous bodily harm.
That sentence was imposed a decade ago, when Pyke was then aged 22, for a knife attack carried out to enforce a drug debt.
Pyke also has previous convictions for affray and assaulting a police constable.
What jurors were NOT told is that, five years ago, Pyke was cleared of murdering a man alleged to have been carried out in similar circumstances to the death of Mr Pierre.
The YEP can now report that Pyke walked free in October 2009 over the murder of cannabis dealer Christopher Elliot on the directions of a judge.
Mr Elliot’s burning body was found in woodland near the Ravenscars, off Roundhay Road - less than a mile from where Mr Pierre was murdered - on November 20, 2006.
The prosecution at the 2009 trial alleged Pyke and at least one other man took part in the fatal attack on Mr Elliot at his home in Borrowdale Crescent, Bramley.
Mr Elliot had been battered to death at his flat by the killers who used a brick, a dumbbell and bottles of champagne.
The body is then thought to have been moved to woods off Roundhay Road before being set alight. It was also alleged that Pyke and others disposed of items including clothing and a samurai sword blade which belonged to Christopher Elliot.
Pyke, then aged 27, walked free after Mr Justice Wilkie directed jurors to return not guilty verdicts against him and his co-accused five weeks into a trial at Leeds Crown Court.
The judge told the jury that the prosecution’s case was based “exclusively on circumstantial evidence.”
He said: “Such evidence may properly be considered but it is both potentially powerful and also potentially dangerous evidence and great care has to be taken in approaching it.”
He added: “I have concluded that no jury properly directed could safely convict any of them so I must direct you to return a verdict of not guilty.”
