Ben Needham: Police search land for missing boy's remains
Experts from police forces across the UK have joined Greek officers in a search for a Sheffield toddler who went missing 21 years ago.
Ben Needham vanished on the island of Kos in July 1991.
Det Supt Matt Fenwick told BBC Look North that a mound of rubble and fields surrounding the Needham family's former farmhouse were being searched.
Dog handlers from South Yorkshire Police were first on the scene as the operation began on Friday morning.
