Former Mountjoy governor John Lonergan has defended prisoners' access to Playstations in jail.
It emerged this morning that 55 of the consoles are circulating in Mountjoy.
The Irish Prison Service is also looking at sourcing some sports equipment to keep inmates occupied.
Ex-governor John Lonergan said he was fully behind the idea.
"(Prisoners) spend a lot of time - up to 18 hours, and sometimes up to 23 hours a day - locked up, with very little occupation in many areas, especially in Mountjoy during the day," he said.
"They have to be occupied in some way. What Playstations do is keep their minds and brains occupied and contribute to keeping people sane."
