Police have reported that three sisters have died following a violent incident at a house in Dublin.
The teenager and his two younger brothers 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 around 12.30pm on Sunday, and described the incident as violent, challenging and traumatic.
A teenager was also taken from the scene to hospital with serious but non-life-threatening injuries.
A man in his 20s was later arrested at the scene by the Gardaí’s Armed Support Unit.
He is being held at Tallaght Garda Station under section 4 of the Criminal Justice Act 1984.
The children’s mother, who was not injured, was also taken to CHI and is currently receiving medical attention.
Gardai said all those involved are believed to know each other and officers are not looking for anyone else in connection with the incident.
The scene at Rossfield Estate remains cordoned off and a forensic examination will be carried out by the Garda Technical Office on Sunday.
Post-mortem examinations should also be carried out.
An Garda Siochana said it has appointed a family liaison officer and will continue to support those involved, along with other state agencies.
