Aaron Brady moved to prison wing with killers Warren Dumbrell and John Dundon

Following his move from Mountjoy Prison to Portlaoise on Friday afternoon, Brady was placed on the C-landing with an assortment of what prison officers called 'high-security, high-risk inmates.'

These include Limerick organised crime boss John Dundon, notorious killer Warren Dumbrell, remand prisoner Peter (Peader) Keating, who is charged with the attempted murder of Hutch associate James 'Mago' Gately, and Thomas Fox, who is serving life for the murder of Gareth Hutch.

Sources have confirmed Brady (29), from Crossmaglen, Co. Armagh, was moved from Mountjoy Prison, where he was housed in the D-block and enjoyed a cushy job in the prison kitchens, on foot of being sentenced to 40 years in prison for the capital murder of Garda Adrian Donohoe.

Brady had spent the past three years in custody in Mountjoy while awaiting trial and sentencing.

The C-landing in Portlaoise is used to house dangerous inmates but is not categorised as a dissident Republican or organised crime wing.

"In Portlaoise, you only get onto the Republican E-wing if they (the current occupants) want it to happen and no such request has been made to the prison authorities on Brady's behalf.

"Similarly, there is no intel as such in Portlaoise that Brady is under the protection of the Kinahan Organised Crime Group.

"Saying that it is only his second day in Portlaoise and he is only getting used to his new surroundings."

Among the most high-profile of Brady's new neighbours is John Dundon, who is serving life for organising the botched murder in which rugby captain Shane Geoghegan was gunned down in 2008.

Warren Dumbrell is also serving a life sentence for the horrific murder of Christy Cawley in October 2006.

He is considered one of the most volatile and dangerous inmates in the prison system and has been kept away from the general prison population for a large amount of his sentence
