Graham Dwyer in single cell in prison

Murderer Graham Dwyer is sharing a landing in Midlands Prison with one of the most notorious sex offenders, who is serving life for raping two children.

Dwyer was taken to the Portlaoise jail — the biggest detention facility in the State — at 8pm on Tuesday and given a single cell on the third landing of E wing.

Midlands Prison houses around 200 of the estimated 350 sex offenders in Irish prisons and a large number of the 300-plus inmates serving life for murder.
