The police chief leading the search for the remains of Ben Needham said 'nothing of significance' was found on the second day of a dig.
A police team is excavating an area of land close to where Ben Needham, from Sheffield, was last seen alive on the Greek island of Kos, in July 1991.
South Yorkshire detectives are working on a theory that Ben, who was 21 months old at the time, may have been accidentally crushed and buried by a digger clearing a building plot nearby.
Ben was playing outside a farmhouse his grandfather was renovating when he went missing.
His family has always believed that he was abducted, but after detectives received a tip-off about the digger they warned Ben's mum, Kerry Needham, to 'prepare for the worst'.
Detective Inspector Jon Cousins, co-ordinating the operation on Kos, said some scraps of fabric found on the first day of the search are still being examined but nothing else was found yesterday.
He said he was overwhelmed at the number of volunteers offering to help the search team.
A local man claimed his friend, who died last year, could have accidentally killed Ben when he was clearing a building plot close to where Ben was last seen alive.
Material moved by the digger was dumped at two sites, which have both been cordoned off.
