A PRISONER is critical in hospital after being battered in the exercise yard in Dublin’s Mountjoy.
The inmate was targeted by at least two others in an incident which sparked chaos across the jail.
Three ambulances rushed to the scene as the victim was rushed to hospital.
Sources told the Irish Sun he is in critical condition and is fighting for his life.
One told us: “He got an awful hiding but what sparked the whole thing is still unknown.
“The man who was attacked is a very difficult individual to deal with so it could have been anything.
“The wider prison population was also going mad as events unfolded, with very high tensions among some.”
While prison authorities have launched a major investigation, they have also called in the gardai.
One line of inquiry into the attack being looked at is a row over drugs.
The attacked prisoner – who is understood to have over 100 convictions – is under guard in hospital with officers.
This morning, an Irish Prison Service spokesman said: “The Irish Prison Service can confirm that an incident occurred at Mountjoy Prison on 06 June 2025 involving a prisoner. The incident has been referred to An Garda Síochána.”
The latest incident in Mountjoy came after a number of separate disturbances at the prison last month.
Thug Trevor Byrne was moved to Portlaoise under armed escort for his safety following the incidents, in the D-wing of Mountjoy, where Kinahan cartel members are detained.
The rows between various rival criminals involved beatings and scaldings with boiling water, with one inmate being brought to hospital on that occasion.
