Five people, including three children, have been injured in a stabbing incident in Dublin City Centre, with one child requiring emergency treatment for her injuries.
Gardaí and emergency services attended the scene at Parnell Square East in the north-inner city shortly after 1.30pm on Thursday.
Three young children, a woman and a man were taken to various hospitals in the Dublin region for treatment.
Gardaí confirmed a five-year-old girl sustained serious injuries and is currently receiving emergency medical treatment in CHI Temple Street.
A five-year-old boy and a six-year-old girl sustained less serious injuries and were taken to CHI Crumlin for treatment. The boy has since been discharged.
A woman aged in her 30s is receiving treatment for serious injuries at the Mater Hospital.
Gardaí added that a man in his 50s, who is a person of interest in the investigation, also sustained serious injuries and is being treated at another hospital in the region.
Investigators are not looking for any other person in connection with the incident at this time. However, the force said it "continues to have an open mind at this early stage of the investigation".
According to The Irish Times, early indications suggest a man attacked a group of young people with a knife and passers-by intervened. The paper adds that a knife was recovered at the scene.
The scene at Parnell Square remains sealed, and a technical examination is ongoing.
An update from Gardaí on Thursday evening said they are appealing for anyone with information on the attack to contact Mountjoy Garda Station on 01-666 8600, the Garda Confidential Line on 1800-666 111, or any Garda station.
The force is also asking for anyone who may have footage of the attack, or the immediate aftermath of the incident, to make it available to investigating officers.
