A prisoner told jail bosses he felt safe just hours before he was attacked and left fighting for his life.
Robert O’Connor, 34, had stopped breathing and was revived after the assault in his cell in Dublin’s Mountjoy Prison on Friday evening. The four men suspected to have beaten him are now in isolation and could be removed for questioning.
The shocking attack stems from a personal grudge over an alleged assault on the outside. A prison source said: “He is in a bad way. He is in intensive care and is critical. When he was being attended to by emergency services he had actually stopped breathing.”
