The Minister for Justice Michael McDowell has launched a review of a number of issues surrounding the trial of the Limerick man Liam Keane who walked free from the Central Criminal Court today.

Keane, aged 19, of Ballysimon, Co Limerick had pleaded not guilty to the murder of 19-year-old Eric Leamy in Limerick in August 2001.

The Director of Public Prosecutions directed that a 'nolle prosequi' be entered after key prosecution witness Roy Behan denied making statements identifying the accused as the man who stabbed Mr Leamy.

Mr Justice Carney said he had never before encountered the likes of what happened in the trial.

He directed the transcript of this and an earlier related trial to be sent to the Director of Public Prosecutions.
