A boy dressed in St Hilda's Secondary School uniform was caught on camera performing a rear naked choke on another boy.
According to content creator Runner Kao, who received the video from one of his followers, the boys were "playing a game of choking".
However, the follower did not provide further context to the incident in their message, including when and where it took place.
What video shows
Without releasing the full footage of the incident, as it was "very, very stressful to watch", Runner Kao posted several screenshots and described what happened in a Mar. 1 TikTok video.
According to the screenshots, the boy being held appeared to be sitting on a bench, while the grappler appeared to be kneeling on it.
In one screenshot, the boy in the chokehold could be seen tapping on the grappler's elbow with his fingers.
Runner Kao commented that the boy being choked did so to signal to the grappler to stop.
However, the boy behind allegedly refused to let him go until the boy being choked "lost […] consciousness".
Additionally, while the boy being choked became limp in the grappler's arms, the grappler apparently continued "laughing hysterically with his friends around him at the toilet", said Runner Kao.
Although the boy being choked eventually regained his consciousness, RunnerKao warned his audience, especially those who are still studying, against such "dangerous games".
"Playing this type of game, right, can lead to very serious consequences, like permanent brain damage," warned the content creator.
Response from MOE
In response to Mothership's queries, the Ministry of Education (MOE) did not disclose when the incident took place or whether it occurred in St Hilda's Secondary School.
Instead, the ministry pointed to a note it published on Parents Gateway at 7:10pm on Mar. 3, titled, "Keeping Our Children Safe — Managing Risky Online Challenges".
In the note, MOE warned parents that there are "some challenges trending online", which encourage children to engage in risky behaviours.
Two of such challenges are the “Blackout Challenge”, a choking game that deprives the brain of oxygen, and the “Skull Breaker Challenge”, which involves two people kicking the legs of a third person, causing them to fall over.
"As they are dangerous and potentially fatal, we are bringing this matter to your attention so that you can watch out for your children should they seek to attempt such challenges, whether as a prank or otherwise," said MOE.
The ministry added that students are reminded through the Cyber Wellness lessons not to take part in such challenges, "stand up against harmful behaviours", and "seek help from trusted adults", such as teachers and parents, when needed.
At the same time, MOE also sought cooperation from parents to "play an active role" in guiding their children to make safe and responsible decisions about risky online challenges.
