At a press conference, police confirmed that a man in his 50s, who is receiving treatment at hospital, has been identified as a “person of interest”. They are currently not searching for anyone else and confirmed they are satisfied that the attack is not terror-related. On Thursday evening, riots broke out in the city centre with a number of Garda vehicles destroyed, while a tram and bus were set alight. Public transport was suspended while shop windows were smashed, with protesters blocking a bridge with construction signs.

Appealing for calm, Irish justice minister Helen McEntee said: “The scenes we are witnessing this evening in our city centre cannot and will not be tolerated. “A thuggish and manipulative element must not be allowed use an appalling tragedy to wreak havoc.” The clashes broke out a few hours after the knife attack, which happened outside to an Irish-medium primary school, Gaelscoil Choláiste Mhuire.

She said: “I have been briefed by the Garda commissioner and will remain in close contact with him and senior gardaí. “This attack has shocked us all, and I have no doubt that the person responsible will be brought to justice.
