This astonishing video shows a man riding his motorcycle through a flooded road before tumbling down to the ground as shocked locals rush to help.

Surveillance camera footage captured in the city of Changsha, in Hunan, China, shows the man navigating the vehicle along the waterlogged street on April 16.

However, just moments later, he can be seen disappearing into the water after apparently driving into a drainage ditch that he could not see because of the high water.

Warnings shouted by locals do not come quickly enough, and one man can be seen rushing over to try and help him out of the water after his bike sent to the bottom and was swept downstream.

A witness told Chinese media: 'Fortunately, villagers passed by, and both the man and the car were rescued.'
