SHOCKING: Mother saves son before escalator swallowed her alive

A shocking video showing a mother saving her son's life seconds before she was swallowed by an escalator in a mall in China has emerged.

In the 30-second closed-circuit television (CCTV) footage, a woman is seen lifting up a boy as she steps off after reaching the top of an escalator when a metallic floor plate collapses under her feet.

The mother fell into the gap, got stuck in the hole, but was able to push her son towards a shopping assistant who was standing near the killer machine.

The boy was dragged to safety. Unfortunately, his mother, identified in recent reports as 31-year-old Xiang Liujuan, died after other employees of the upscale AZG Mall failed to save her.

According to a local paper, it took rescuers nearly four hours to find the woman's remains in the escalator shaft.

Mall management has yet to release an official statement regarding the accident, but city officials reportedly blamed the tragedy to human error.

Allegedly, the maintenance personnel failed to tighten the lock screws of the floor plate.
