Horror as youngsters crushed under collapsing human pyramid
A human pyramid made up of more than 150 students came crashing down to the horror of a school assembly.
The terrifying incident was caught on camera and showed the very last student climbing to the top of the human structure before it collapses.
The video shows the boy attempting to steady himself and raise a flag atop the ten level structure before it begins to wobble.
Seconds later, a collective scream can be heard from those assembled to watch the display all 150 pupils collapsed to the ground.
The incident occurred at a high school in Yao City, Japan on September 30.
One student fractured an arm and five others suffered injuries according to Japanese media reports.
Human pyramids practised regularly in Japan as part of gymnastic classes, and figures from 2012 show that more than 6,500 students were injured performing the stunt.
