Duke of Edinburgh award scheme walker injured in Snowdonia

The incident happened near Cnicht mountain in Snowdonia

A teenager taking part in a Duke of Edinburgh Award activity in Snowdonia has been airlifted to hospital with a suspected broken ankle.

The 17-year-old, who was part of a walking group, was descending a hill east of Beddgelert on Saturday.

Members of Aberglaslyn Mountain Rescue Team made him comfortable before he was taken by a helicopter from RAF Valley to Ysbyty Gwynedd in Bangor.

Rescuers said the ground was saturated from rain, and treacherous underfoot.

There were six walkers in the group, all teenagers believed to be from Northamptonshire.

The incident happened near Cnicht mountain at around 17:20 BST on Saturday and mountain rescuers were stood down at 20:00 BST.

"The ground is extremely wet and they're [those doing the Duke of Edinburgh Award] carrying a lot of weight," said Iwan ap Trefor, one of the mountain rescue team.

"It was actually dry yesterday - it's just the amount of rain we'd had overnight and on Friday, and we've had so much rain in the last two months or so.

"We strapped him up and took him to the helicopter and the helicopter took him to the hospital."
