KOS, GREECE - OCTOBER 06: A South Yorkshire Police officer watches on as bulldozers clear large concrete rubble at a new second search site approximately 1km from the farmhouse search site of missing toddler Ben Needham on October 6, 2016 in Kos, Greece. The 21 month old toddler from Sheffield vanished on the Greek island in July of 1991. A 19-strong team of police officers, forensic specialists and an archaeologist have been searching an olive grove next to the farm for the past eleven days and have now begun work on a second site, where rubble from the farmhouse was deposited in the days after Ben Needham's disappearance.
