Hollie Dance, Archie Battersbee's mother, has accused social media giants of failing to tackle deadly online challenges like the one that left her son in a coma. The 46-year-old said she believes there have been other deaths linked it, with many more left brain damaged.
Archie, 12, spent more than four months in a coma after he suffered brain damage in an incident at home in Southend, Essex.
He died on August 6 when medics withdrew life support.
