No sign of missing teenager

Rescue teams are searching the loch and countryside

The search is continuing for a teenager with learning difficulties who has gone missing at a beauty spot in Scotland.

Adam Shad, 15, from Gateshead, vanished on Tuesday evening from a campsite on the banks of Loch Lomond.

The youth's family raised the alarm at about 2100 BST on Tuesday after he went missing in the Ardlui area.

A search was launched involving police mountain rescue teams, the coastguard and the Luss rescue boat.

Adam had been taken on holiday by his mother Janette, stepfather Terence Cooper and brother Joseph, 11, to recover from a road accident last December when he was hit by a car.

Since then, he has suffered from learning difficulties.

The rescue teams stepped up their search of the loch and surrounding countryside on Wednesday, with police underwater divers joining the operation.

Janette said: "He loses track of time and he forgets where he is so I'm hoping that he's got lost and I'm hoping that there's anyone out there that can keep an eye on him.

"He's only got a light pair of tracksuit bottoms on and he's got nothing on his feet."

She recalled how they tried to watch Adam as he climbed a hill opposite the campsite.

"One minute he was standing there waving to me and then he was up the hill and we could hear him, we were shouting 'Adam Adam' ... but that was it."

Adam was last seen at about 1700 BST on Tuesday and is described as 5ft 4ins tall, of slim build, with black hair and brown eyes.

The family had been at the Ardlui Holiday Home Park since Saturday and were due to leave on Tuesday but stayed on because of the warm weather.

Strathclyde Police said the search would be postponed for the night at 2100 BST and resume at 0700BST on Thursday morning.
