This is the shocking moment a young child screams in agony after getting his leg trapped in a moving escalator.
The painful footage, captured in China, shows that most of the boy's leg below his knee is caught between the metal stairs.
His mother holds onto him to try and support his weight as he howls in distress.
The video shows that the escalator's emergency button has been pressed so that the stairs have stopped moving.
But it also highlights just how much of the boy's leg is trapped - preventing him from pulling it free.
Instead she waits for the emergency services to arrive, who were presumably forced to cut away at the escalator to remove the boy's leg.
Little information has appeared online surrounding the incident, since the footage emerged on LiveLeak.
Some viewers suggested there was a design fault with the escalator, which caused the boy to get his leg trapped so severely.

Oh china. You were suppose to be the best at tech. Guess that only applies to export items.

I've never heard of escalator accidents outside of China. Has anyone? Wondering if China makes them differently to western countries.

China should just give up on escalators and elevators until they have discovered "safety regulations"....

Maybe as a warning to others? Maybe so the parents can sue?
