It has been claimed that Greek detectives are examining theories ranging from 'serious crime to accidental death' in an effort to solve the case which has tormented Ben's devastated family since the early 1990s.
However, it has been suggested that the apparent lack of direction in the case has been 'damaging to the credibility' of the investigation in Greece.
It is hoped that Ben, who went missing on a family holiday in Kos aged just 21-months, will be found alive 24 years after his devastating disappearance, with his heartbroken family maintaining their beloved son and grandson was abducted from outside the farmhouse they were helping to renovate.
In an effort to solve the case, South Yorkshire Police were granted £700,000 from the Home Office earlier this year so that they may support Greek authorities in their enquiries.
Recent reports suggested that British authorities were following a direct line of enquiry, but it appears both police forces have come under criticism despite potential developments.
According to the Sunday People, a recent report commented on the unsolved case, saying: "The fact that after more than 20 years we are no clearer about the reasons for Ben’s disappearance is... damaging to the credibility of the Greek police investigation and indirectly South Yorkshire Police."
A spokesman for the Foreign Office extended his deepest sympathies to the Needham family and asserted their welfare was of the highest priority saying: "We have the deepest sympathies with Ben Needham's family and continue to offer them consular support."
