There was widespread sadness across the Northern Ireland Ambulance Service (NIAS) and beyond at the passing of their friend and former colleague Seamus McAllister.

Leading the tributes in a social medai post, the NIAS said: "Staff across NIAS have learned, with great sadness, of the passing of friend and colleague Seamus McAllister.
"Seamus had a long and distinguished career in the Ambulance Service serving in many roles but particularly as Divisional Training Officer and Clinical Training Manager.
"Seamus passed away peacefully on Saturday morning following a short illness. Seamus was a hugely popular and well respected member of the NIAS family.
