A toddler boy has been killed in China after getting stuck under a moving toy train in an amusement arcade, according to reports.

The child, described to be nearly two years old, had been taken to the arcade by a family member on July 8.

He was playing on the train track alone at the time of the accident, according to a surveillance video posted by Chinese news site The Paper.

The accident took place at around 7:30pm in Pi County, Chengdu.

A family member had taken the boy to play in the arcade, according to another report by Sina.com, quoting Chengdu Evening News.

The family member appeared to be a middle-aged woman.

The woman took the boy to ride on the toy train for a while before helping him get off the train.

She then left the toddler to play by himself in the arcade.

The boy climbed back to the train track unattended.

He was hit by the locomotive before being pushed along the track for a few seconds. Eventually, he became firmly stuck underneath the train.

Shocking: The boy's family member was standing with her back towards the child and didn't realise the accident. The child was pronounced dead after being sent for medical attention

The family member appeared to be looking after her belongings with her back towards the boy. She didn't notice the accident.

A few adults could be seen standing nearby playing arcade games, and they didn't see the accident either.

After a minute or so, the middle-aged woman realised the boy had gone missing and started searching for him, said Sina.

It's understood that the child was pronounced dead after being sent for medical attention.

The toddler's family and the shopping mall who manages the arcade are said to have settle the matter privately.

The arcade has been closed after the accident.
