The moment an 85-year-old man was mown down by a cement truck while crossing the road in Xi'an in northwest China has been captured on CCTV.
It is thought he passed so close to the truck the driver didn't see him. Police say the driver may not be charged with hit and run. Amazingly, after disappearing under the truck, the injured man managed to sit up and appeared to call for help.
He was rushed to hospital after several passers-by carried him off the road.
This video shows the moment the pedestrian was hit and how members of the public came to his aid afterwards.

The man passed one vehicle without incident, and is shown just seconds away from passing in front of the lorry.
Moments later, he was directly in front of the truck. The driver does not appear to have noticed him.
And then he disappeared from sight.
A high school student saw the accident and rushed to help. Several other passers-by also helped lift the injured man off the tarmac.
Two other students ran to a nearby hospital and fetched a stretcher to transport him. Local reports suggest his legs were seriously injured and had to be amputated.
