An eight-year-old boy died in an accident in a fast-flowing river on Saturday afternoon on the Kerry/west Cork border.
The boy, named as Benjamin Cunnane, was with his father, an electrician, and two other adults.
They were working on a river turbine in the Borlin valley on the Kilgarvan to Bantry road, a narrow mountain pass.
Details are unclear but it appears the boy wandered into the river, the Borlin.
He was found a short time afterwards by his father and was taken to Bantry General Hospital at around 3 p.m. on Saturday. Local gardaí say he was pronounced dead two hours later.
The dead boy was the youngest of four children of Gerry and Isabel Cunnane of Kilgarvan.
Councillor Danny Healy-Rae, whose children attend the same school as the dead boy, said local people were "numbed and shocked" by the tragedy.
A post-mortem was carried out at Bantry General Hospital yesterday.
