A man aged in his 20s has been arrested in connection with the investigation into the death Sharon Whelan (30) and her daughters Nadia (2) and Zarah (7) at Roscon, Windgap, Co. Kilkenny on Christmas Day.
The two young girls died as a result of smoke inhalation following a fire but postmortem results suggest that Ms Whelan was already dead by the time the fire destroyed her remote rented home near the village of Windgap on the Kilkenny-Tipperary border.
The three bodies were pulled from the house at about 9am on Christmas Day when locals saw the property engulfed in flames.
A man was arrested late this afternoon and is currently being held under Section 4 of the Criminal Justice Act at Kilkenny Garda Station. He can be detained for up to 24 hours.
Gardaí have renewing their appeal for anyone with any information to contact them at Kilkenny Garda Station on 056 777 5070.
