Andrew Gosden: The 14-year-old boy who disappeared

On 14 September 2007, 14-year-old Andrew Gosden walked out of his family home in Doncaster, boarded a train to London with a one-way ticket and then simply vanished.

A short sequence of CCTV stills captured that morning at King's Cross station represent the last known sighting of the schoolboy.

A decade on, his disappearance remains a mystery.
