The detective who fatally shot killer Mark Hennessy will have to explain to the Garda Síochána Ombudsman Commission (Gsoc) that he honestly believed either his life or the life of another person was in “immediate danger” when he opened fire.

Gardaí may have to move out of their central Dublin headquarters building if agreement cannot be reached over lease arrangements with a private company which bought the property, the Commercial Court has heard.

Gardaí are gathering and examining CCTV footage from around the phone box where a caller issued a bomb warning in the name of Islamic State to the Kildare plant of computer giant Intel.
