Mourners at the funeral of a 13-year-old boy, who died after an incident at his school, have been told he was "forever smiling."

Oisín McGrath's parents, Nigel and Sharon, and his sisters, Cairenn and Ciana, were joined by hundreds of people at the church in Belcoo in County Fermanagh.

His classmates and Gaelic football teammates formed a guard of honour outside and a school choir sang as his coffin arrived.

The village has been stunned by the playground tragedy, which is still being investigated by police.

A 17-year-old sixth form student from the same Enniskillen school was questioned after the incident but has been released on bail, pending enquiries.

The year nine student was taken to hospital from St Michael's College at lunchtime on Monday and died on Thursday evening.

On medical advice, his parents made the agonising decision to withdraw their teenage son's life support and donate his organs for transplant.

Father Seamus Quinn paid tribute to the schoolboy, a budding musician and sportsman, and said the grief of his school friends spoke volumes.

He said: "He was forever smiling, a big wide happy grin etched on his face.

"He was a natural, unaffected young lad, quiet and easy to be with, the kind of smile that drew the best out of you, whether you were young or old.

"Because of his parents' incredibly selfless and faith-based decision, Oisin's falling on the ground and dying like a grain of wheat has brought life to five other human beings."
