Jet of flames burns little boy's hand after putting key in bike charger socket

This is the shocking moment a jet of flames burns a little boy's hand after he puts a key into a bike charger socket.

The father acknowledged that the boy likes to play with keys and did not realise the child might try to stick one inside the socket when left alone with the vehicle while he went inside to get a cigarette in Zhangzhou, Fujian province, China, on September 26.
