Shocking video shows metal gate unhinging, falling on child

Video footage captures the shocking moment a metal gate unhinges and falls on top of a child in Vietnam. 

Two children can be seen swinging on the heavy gates, before one falls on top of the unsuspecting youngster.

Their father Huu Nhan said: "My son had a head injury and had to stay at the hospital. It was very difficult but I hope that this served as a warning to other parents to be more careful."

See what happens in the video above.
