A teenager has died after joining in a variation of the latest internet craze, the ice bucket challenge.
Cameron Lancaster is believed to be the first victim of the trend, in which people film themselves having ice water poured over their heads for charity.
The 18-year-old was found dead after jumping into a disused quarry.
Mr. Lancaster disappeared under the water at Prestonhill Quarry in Inverkeithing, Fife, on Sunday.
He is thought to have jumped feet first off a cliff into shallow water, in response to the internet mania that has swept around the world.
His body was recovered after a four-hour search. The death of Mr. Lancaster, from Burntisland, a small coastal village in southern Scotland, comes amid mounting criticism of the challenge. Some observers say it has begun to stray from its original aim of raising awareness and money for the neurodegenerative disease ALS, or motor neurone disease.
In recent weeks, participants have filmed themselves performing increasingly risky stunts in new variations of the challenge.
It is understood that he took part in an ice bucket challenge before leaping into the water from 25-metre high cliffs.
