One of the longest running missing person enquiries involves the disappearance of Doncaster teenager Andrew Gosden.
Andrew went missing in 2007 when he was 14 years old and boarded a train to London.
There have been no positive sightings since.
Andrew has an unusual and distinctive right ear. He is deaf in his left ear and struggles to locate the direction of sounds.
He used to speak quickly and quietly, without a strong accent, which is unlikely to have changed. He is highly intelligent.
Anyone with any information on the whereabouts of any of the missing men should call South Yorkshire Police on 101.
