A Philadelphia family is suing TikTok after their 10-year-old daughter dies trying a video challenge posted on the social media site.

The challenge, called the 'blackout challenge," encourages users to asphyxiate themselves, pass out and regain consciousness, while on camera. Nylah Anderson was found unconscious in her mom's bedroom closet hung from a purse strap. Tawainna Anderson, Nylah's mother, says the video platform is negligent and has a 'defective design.

Nylah saw the challenge on the app's 'For You' page. According to the lawsuit, the company's algorithm sent the video to the 10-year-old.

Last year, a 12-year-old boy died trying the same challenge. He used a shoelace to choke himself. Anderson says TikTok is aware of the dangers but has made no efforts to change.
