Minister for Justice Alan Shatter has received a final report from the long-running State inquiry into the death of Gary Douch in Mountjoy prison.
RTE's This Week understands that the long-awaited Commission of Investigation report was sent to the minister by the commission's chairperson, Grainne McMorrow SC, last week.
The inquiry was established back in 2007 by the then Minister for Justice Michael McDowell, to look into the circumstances leading to Mr Douch's death.
The 20-year-old was beaten to death by fellow inmate Stephen Egan, who was later found guilty of Mr Douch's manslaughter by reason of diminished responsibility.
Mr Egan, who is now aged 30, formerly of Belcamp Crescent, Coolock, killed Mr Douch, who was also from the Coolock area, after both men were placed in a cell with a number of other inmates on 1 August 2006.
Mr Egan's trial heard that he was diagnosed with a schizo-affective disorder.
It also emerged that he had been transferred to the cell along with the other inmates without anti-psychotic medication which had been prescribed to him at the Central Mental Hospital.
The inquiry's terms of reference included a wide-ranging examination into how prisoners with mental health issues and other vulnerable inmates are managed within the prison system.
The final report is believed to be around 500 pages in length.
It is believed that the vast majority of staff who interacted with Mr Douch in Mountjoy prison, or with Mr Egan during his time in both the prison and the Central Mental Hospital, will not be identified by their names in the report.
