A Northern Irish event rider has died, two weeks after a fall at Glenarm Castle Horse Trials.

Stephen Moore, aged 45, died of a heart attack on Friday after collapsing at home. It is thought he also had broken ribs and a punctured lung.

John Wright, chairman of Eventing Ireland, said: “We extend our heartfelt sympathies on behalf of the whole equestrian community to the family of Stephen Moore, who died tragically in Coleraine hospital on Friday 15 August, and also to his colleagues in the northern region of Eventing Ireland.”

It is not yet known whether Mr Moore died due to complications from injuries sustained at Glenarm.

He fell from his horse Whoa Nelly at the Co Antrim event on 2 August, sustaining a broken collar bone.

If connected to the fall, his death would be the 16th internationally in eventing since August 2006.

Stephen’s twin brother Sam was killed in a fall at Blenheim in 1997.
