This is the terrifying moment a nine-year-old boy fell onto an underground railway track while concentrating on playing a game on his electronic device.

Miraculously he avoided suffering either a deadly electric shock or being hit by an oncoming train.

The boy named Lev reportedly touched an 825-volt electric rail with a protective cover, before running along the line and being plucked to safety by a member of staff.
