A cleaner in Shanghai had his foot amputated yesterday after another escalator malfunctioned.
CCTV footage shows the cleaner mopping the panel of an escalator before it collapsed and trapped his foot underneath.
Some may find the footage distressing.
It took almost 20 minutes for emergency services to free the man from the escalator before he was taken to hospital. Surgeons were unable to save the man's foot.
This follows a similar incident from last week in which a mother pushed her child to safety as the same floor panelling collapsed, claiming her life.
An investigation is now under-way.
