Leroy Dumbrell claims he was detained in inhumane conditions in Castlerea Prison

One of the country's most violent prisoners is suing the State for alleged ill-treatment while he was behind bars.

Leroy Dumbrell launched a High Court legal action against the State, the Minister for Justice, the Irish Prison Service and the governor of Castlerea Prison.

Legal papers were submitted last week, but it is not known exactly on what grounds Dumbrell (29) is intending to sue the State.

However, sources believe the dangerous thug will allege he was detained in inhumane conditions when he was held in solitary confinement in the Co Roscommon prison when he was there from December 2009 to August 2010.

He was transferred to Castlerea after he orchestrated riots in Mountjoy, an offence for which he received a suspended sentence in October 2012.

Three prison officers were injured when between 15 and 20 inmates armed with wood and metal bars became involved in a violent confrontation with the inmates of a cell on December 27, 2009.

Dumbrell is considered one of the most violent and disruptive inmates in the prison system.

While serving various multiple sentences, he has received more than 100 P19 Reports, which are issued when disciplinary action is taken against a prisoner.

Dumbrell has been disciplined for acts of violence and incitement to cause a riot, emptying his chamber pot on the prison landing, being caught in possession of drugs and of being in possession of mobile phones as well as numerous other breaches.

Such is his fearsome reputation that Mountjoy staff walked out of their jobs for four hours after management placed Dumbrell in a special unit in the prison in September 2010.


Dumbrell, also known as Leroy Roche and whose last address was Carriglea Gardens, Dun Laoghaire, is serving a seven-year sentence for stamping on a man and threatening to kill a garda.

The sentence was imposed by Dublin Circuit Court in late April when he pleaded guilty to one count of violent disorder on November 27, 2013.

He also admitted threatening to kill or cause serious harm to Ballymun-based Det Gda Ronan McMorrow on May 5 last year.

The violent disorder conviction related to an incident in which Dumbrell stamped on the victim's leg as he lay on the ground in Ballymun. The assault was captured on CCTV.

Dumbrell later made threats that Det McMorrow would "need a body bag". He warned the officer: "You bring me back to court and you'll regret it. Mark my words, you c***."

He is a member of one of Ireland's most notorious crime families.

His brothers Jeffrey (36) and Warren Dumbrell (42) are serving life sentences for the murder of Christopher Cawley (33) on October 29, 2006.

Mr Cawley was stabbed on the stairway of the flat complex where he lived in Inchicore.
