A heroic policeman used his own body to protect an old man from being attacked by a runaway buffalo before shooting it dead in eastern China.

The video, shot in the city of Jinhua in Zhejiang Province on March 5, shows a buffalo wandering along the road before suddenly attacking a biker.

Another clip shows a policeman chasing after the out-of-control buffalo, then running in front of the old man to protect him from being hurt by the buffalo.

According to reports, the buffalo escaped from a villager's house and ran across several villages, knocking over an old man and a child before damaging three scooters.
