A bus with 50 passengers nearly fell into a river after a man hit the driver in eastern China.

In the CCTV video, captured in Wenzhou City in Zhejiang Province on February 4, a man suddenly strikes the driver on his head while the bus is moving. The bus driver then presses the brake immediately to stop the vehicle.

Another dash-cam clip shows the bus stops barely less than two metres away from a river on the side of the road.

According to reports, a man named Cheng asked the driver to stop and wait for his friend Ye, who had gone to the toilet, but was refused as the driver insisted on moving forward according to the timetable.

Then Cheng started to swear and another friend of him named Huang then hit the driver, causing the bus losing control and nearly dropping into a river.

Fortunately, no one was injured and police have arrested Huang.
