This is the shocking moment a nine-year-old boy leapt from a moving train after his friends allegedly bullied him to jump.

Footage shows the schoolboy tumbling from a window into the grass a few meters from the tracks in Nakhon Si Thammarat, southern Thailand.

Driver Jinnawat Chinnapong was waiting for the train to pass when the incident happened in front of him and was captured by his dashboard camera.

He said: "This is so dangerous. All of us waiting at the red light was shocked. The boy could easily have been killed."

Luckily, the boy landed on the grassy part of the roadside and not on the concrete so he was only slightly injured with minor bruises after the jump.

Jinnawat rushed to call the emergency services to assist the young boy with first aid treatment before taking him to the hospital.

His parents were also called to come to the hospital before he was interviewed by the authorities about the incident.

The boy said he took the train with his two other friends who called him a ''girl'' and jeered him to jump from the window to "show he is brave."

The three boys agreed to jump together but he was tricked and the other two did not jump after him.

The police said they will further investigate the incident and contact the parents of the two other boys who allegedly bullied the victim.
