Three sisters have died following a violent incident at a house in Dublin, police have said.
The teenage girl and her two younger siblings were taken by ambulance to Children’s Health Ireland (CHI) in Crumlin, but all three were later pronounced dead.
Officers were called to a property on the Rossfield Estate in Tallaght at about 12.30am on Sunday, describing the incident as violent, challenging and traumatic.
A teenage boy was also taken from the scene to hospital with serious injuries, however they are not thought to be life-threatening.
A man in his early 20s was subsequently arrested at the scene by the Garda Armed Support Unit.
He is being held at Tallaght Garda Station under Section 4 of the Criminal Justice Act 1984.
The mother of the children, who was not injured, was also taken to CHI and is currently receiving medical treatment.
