The recent internet craze called 'Neknominate' has raised concerns as people are risking their lives by performing the latest stunt.
In the videos, which have been posted on a Facebook group called 'Valleys neck and nominate', people are seen downing huge amounts of alcohol before 'nominating' someone else to try to outdo them, Metro.co.uk reported.
In one video, a man is seen biting the head off a dead chicken, which was killed when he was one day old, before eating it, and is also seen downing a can of premium Kestrel lager and almost a pint of vodka containing three raw eggs and a cigarette he has just stubbed out on his tongue.
Some people are seen drinking their own urine and downing a pint of Sambuca, in other alarming videos.
