South Yorkshire Police have said they now believe Ben Needham, the Sheffield toddler who disappeared 25 years ago, died in an accident at the time. Detectives who had travelled to the Greek Island of Kos confirmed that the search is over as they conclude the young boy was killed accidentally by a digger driver near the farm house where he disappeared. Ben was 21 months old when he went missing during a family holiday in Kos on 24 July 1991.
