A Chinese mother has died after becoming trapped following the sudden collapse of an escalator at a shopping mall. The woman fought to push her son out of danger before being swallowed by the mechanism. The woman’s body was recovered more than four hours later, according to witnesses who posted pictures on China’s Twitter-like Weibo platform.

The 15-second video was uploaded to YouTube today, and claims to show CCTV footage from the Jingzhou Shashi Anliang department store in China. The video shows the mother and boy reaching the top of the escalator, before the floor in front collapses.

As she fell half-way through she pushed her son forward, and a nearby shop assistant dragged him to safety. The mother manages to push the child to safety, but is swallowed up into the machinery, despite the efforts of staff. It is not the first time a faulty escalator has claimed someone’s life.
