Gardai have clarified that two sisters and a brother died tragically in Tallaght early this morning.
Officers have arrested a man in his 20s in connection with the deaths.
8 year-old twins , a boy and a girl, along with an 18 year-old woman died this morning in what Gardai are calling a ‘violent incident’ on Rossfield Avenue.
The siblings were rushed to hospital where they were pronounced dead.
A 14 year-old boy was also brought to hospital, where he’s being treated for non life threatening injuries.
The children’s mother wasn’t injured at the scene but is also receiving medical treatment.
After being alerted of the incident at around half past midnight, a man in his early 20s was arrested at the scene after the Garda Armed Support Unit intervened.
All involved are believed to have been known to each other.
One of the upstairs windows of the house has been damaged, and a forensic investigation is ongoing.
