An inmate at Mountjoy Prison has died after being attacked at the jail last week.
The man, who was in his 30s, was taken to the Mater Hospital following the assault on Friday evening but has since passed away.
The Irish Prison Service says the incident continues to be investigated by the IPS and Gardaí.
Stephen Breen, crime editor with the Irish Sun, says the attack happened just two days into the man's sentence:
"Convicted criminal Robert O'Connor was attacked by three other inmates. He suffered a very vicious beating. He was brought to the Mater Hospital and had been held in the intensive care unit of the hospital from last Friday. In the early hours of this morning, his life support machine was turned off and he passed away."
