Gardaí were on Thursday night still trying to establish a motive for a stabbing attack that left three infants and a woman in her 30s seriously injured. One of the children, a five-year-old girl, was left fighting for her life.
In the wake of the attack, teams of gardaí were trying to quell serious violence in Dublin city centre on Thursday night after the stabbing attack.
The suspect for the lunchtime stabbing, an individual whom Garda Commissioner Drew Harris said was a man in his late 40s, remained under armed guard in a Dublin hospital on Thursday night after sustaining multiple injuries in the aftermath of the attack.
Gardaí are trying to determine whether there is any relationship between the chief suspect, a naturalised Irish citizen who has been in the State for 20 years, and anyone at the scene or the school.
