A 13-year-old boy is in a critical condition in hospital following an incident at a secondary school in Co Fermanagh earlier this week.
It is understood that second year student Oisin McGrath was injured in a football kickabout in the playground of St Michael's College at Chanterhill Road in Enniskillen on Monday afternoon.
The school said in a statement that Oisin became unwell while a group of students were playing at lunchtime.
A 17-year-old boy was arrested following the incident.
He was later released on bail pending further inquiries.
Oisin, a keen Gaelic footballer from the village of Belcoo, is being treated in the Royal Victoria Hospital in Belfast.
Belcoo O'Rahilly's GAA club urged members to pray for him.
"The club asks all its members to keep Oisin McGrath in their thoughts and prayers as he is currently in the Royal Victoria Hospital," said a club statement.
