A 12-year-old boy has died after reportedly taking part in an internet game which starves the brain of oxygen, according to family and friends.
Karnel Haughton, from Birmingham, reportedly lost consciousness and suffocated.
Police are treating his death as 'unexplained', but reportedly he was found in his room by his mother Gemma Haughton last week.
He died later in hospital.
The 'game' involves choking yourself and posting the video on social media.
Friends of the family have set up a GoFundMe crowdfunding page to raise money for his funeral, and to pay for his grandmother to fly over from America to pay her respects.
