Cyber safety experts have warned about a new and dangerous trend on social media that has lead to at least one death and multiple injuries.
The "Skullbreaker" game, which has gone viral on TikTok, involves three people standing side-by-side tricking the middle person into jumping and having their legs kicked from underneath them.
Brazilian TV station Costa Branca has reported that a 16-year-old girl died because of the prank in December.
Another incident, in Venezuela, was recorded and shared on TikTok of a young schoolboy playing the game and crashing down onto hard concrete. The Mirror reports that the boy ended up in the intensive care unit.
