A worrying trend among young people on TikTok led to the death of 11-year-old Tommie-Lee Billington from Lancaster, England.

This comes after two teenage girls also lost their lives when participating in the same “challenge” on the app, reports The Sun.

It all started when 11-year-old Tommie was at a friend’s house for a sleepover on Saturday. The boys then “huffed” after seeing a challenge on the TikTok app.

This involves inhaling dangerous gases or solvents that cause a high. Examples include dry shampoo, spray deodorant, and glue.

After Tommie and his friend decided to participate in the trend on TikTok, the boy’s heart stopped immediately. According to medical staff, he died instantly. Now, the family is mourning the tragic passing of the 11-year-old.

His mother, Sherry, has urged other parents to talk to their children and stop their children from using TikTok. She took her plea to Facebook, writing, “This cost my son his life from trying something other kids are doing. Please talk to your children about the consequences of this. It is beyond me why anyone would even try this! It’s so dangerous!”

“I have never felt pain like this. My whirlwind. I just love you so much mate. My baby boy. You will forever be in my heart. I will make sure to the best of my ability that your name and your beautiful face will become the reason that other children’s lives will be saved and other families don’t have to suffer this deep, deep hurt,” she writes on her Facebook page.

Rest in peace, Tommie. All our thoughts are with the family in this difficult time. Now, let’s work together to spread this incredibly important message so that no other children try this life-threatening trend!
