Two children and a teenager have been killed in a fatal assault in Tallaght.

At around 12.30am this morning, Sunday 4th September 2022 Gardaí were informed of a violent incident at a residence in the Rossfield Estate, Tallaght, Dublin 24.

The three siblings were taken by ambulance to Crumlin Children's Hospital, where all three were later pronounced deceased.

A male teenager was also taken from the scene to Tallaght Hospital with serious, but what are believed, at this time, to be non-life threatening injuries.

Following an intervention by Garda Armed Support Unit members, involving the discharge of "less than-lethal" devices, a male in his early 20s was arrested at the scene.

He is currently being detained at Tallaght Garda Station.

The children's mother, who was not injured at the scene, is currently receiving medical treatment in Crumlin Children's Hospital.

Everyone involved in the incident are believed to know each other.
