A man in his 30s has been arrested in connection to the death of 37-year-old woman Seema Banu and her two children, 11-year-old daughter Asfira Syed and six-year-old son Faizan Syed.
The man is currently being detained under the provisions of Section 4 of the Criminal Justice Act, 1984 at Dundrum Garda Station.
The bodies of the three were discovered last month at a property in Llewelyn Court, Ballinteer, south Dublin.
Shortly after, Garda launched a murder probe into the deaths after post-mortem examinations were completed and found the cause of death to be strangulation.
A spokesperson for An Garda Sochna has said that investigations are ongoing and no further information can be provided at this time.
