A 12-year-old boy has died after reportedly taking part in a dangerous online craze which cuts off oxygen to the brain.
Karnel Haughton, from the Tyburn area of Birmingham, is believed to have lost consciousness and suffocated.
Friends and parents have now shared warnings about the potentially lethal game in which youngsters film themselves choking and post the videos on social media.
Karnel is thought to have been playing the 'game' in his bedroom when he lost consciousness.
He died later that day after being rushed to hospital by his mum Gemma.
Police are treating his death as 'unexplained'.
A family friend said: “It was his mum who found him at home. He was apparently playing the ‘choking game’.
“Karnel was such a witty and happy young boy and really close to his brother and sister.
