Overview
- Gardaí, who added a fifth arrest Wednesday evening, now have five people in custody for questioning under laws that allow up to seven days of detention.
- The investigation expanded Tuesday when officers detained three men in their 20s and 30s and a teenage boy at Garda stations in the midlands under the Criminal Justice Act 2007.
- Detectives say the December 6, 2025 blaze began after an attacker threw a petrol bomb through a front window, and CCTV shows two hooded figures smashing glass and tossing a burning object.
- Four-year-old Tadhg Farrell and his great-aunt Mary Holt, 60, died in the front room where the fire started, and Tadhg’s grandmother, Pauline Holt, suffered serious burns.
- Justice Minister Jim O’Callaghan called it a murderous attack and said Gardaí are examining a possible link to people involved in the drugs trade as inquiries continue.
