Ben Needham: Police begin Kos excavation
Police teams from South Yorkshire have begun excavation work at a site on the Greek island of Kos, in the hope of finding missing toddler Ben Needham.
Ben was 21 months old when he vanished during a family holiday on 24 July 1991.
Officers now believe he may have been accidentally killed by a bulldozer on a building site, as Danny Savage reports.
