The father of a boy who went missing in the sea while on holiday was rescuing his younger son from the water when he lost sight of the older sibling, it has emerged.
Adam Nash, 35, told the Mirror of the moment he realised 12-year-old Isaac had not made it back to the shore amid difficult conditions on the north Wales coastline.
Isaac and younger brother Xander, 10, from Huddersfield, West Yorkshire, were on holiday in Aberffraw, Anglesey, when the incident happened on Friday lunchtime.
Coastguard rescue teams, RNLI lifeboats, a RAF rescue helicopter and police were involved in the initial search for the youngster, which is expected to continue this morning.
Mr Nash told the paper he and the boys' grandfather tried valiantly to help the pair out of the water.
He said: "I got hold of him (Xander) about three times to get him back. He was grabbing me round the neck. He said he couldn't swim anymore. I was exhausted too. I thought I just don't want to let go of him.
"When I got my feet on the ground I was massively relieved. Xander said to me, 'I thought I was going to die'."
Mr Nash said he turned around to see his father washed up on rocks.
"My dad came round and his face was just screwed up and there was blood dripping down him from his arms and legs. And he said, 'I couldn't save him, I couldn't save him'," Mr Nash said.
Rescue crews described how the initial search had been carried out in poor conditions.
