A 13-year-old boy who took part in a "blackout challenge" on TikTok has died while a 17-year-old who did it with him remains hospitalised in a serious condition.
Both unnamed boys suffered cardiorespiratory arrest after taking part in the challenge while filming themselves.
The challenge also referred to as the "choking challenge" and the "pass-out challenge", involves participants asphyxiating themselves until losing consciousness.
