Disappearance of Ben Needham

Human blood has been found on a toy car and sandal believed to have belonged to toddler Ben Needham, who disappeared on the Greek holiday island of Kos 26 years ago, according to British media.

A UK police team probing the more than two-decade old disappearance of a British toddler on the Greek island of Kos said Monday the boy was likely killed in an accident.

However, investigators have not found the body of Ben Needham - who was 21 months old when he vanished near a farmhouse where his family was staying in July 1991 - and they said the investigation is continuing.

British police on Monday wrapped up a renewed investigation into the disappearance of toddler Ben Needham on the island of Kos in 1991, saying the boy probably died in an accident involving a digging machine.

Detective Inspector John Cousins, from South Yorkshire Police, told reporters that it was his "professional belief" that the boy died in a digger accident.

An undated handout photograph made available by Britain's South Yorkshire Police Monday showing a pair of sandals, they have had specially made, and which they believe resemble the pair British toddler Ben Needham was wearing when he disappeared on 24 July 1991, near the village of Iraklise, on the island of Kos, Greece.

The family of missing toddler Ben Needham say they are “eternally grateful” for the volunteers who have been helping with the police search. A team of 19 South Yorkshire Police officers, forensic specialists and an archaeologist are excavating farmland near to where he was last seen playing. Members of the Hellenic Rescue Team and Red Cross are assisting.

Ancient graves have been unearthed on the Greek Aegean island of Kos in a new search for a British toddler who went missing over two decades ago, police said Friday.

"We have actually found some archaeological remains, weve got four graves which date back at least 1,500 to nearly 2,000 years ago," Detective Inspector Jon Cousins said in a video released by the South Yorkshire Police.

Members of the South Yorkshire Police and a Greek search team are seen Thursday on the site of an excavation on Kos launched as part of a renewed investigation into the disappearance of Ben Needham, a 21-month-old British toddler who went missing in 1991 on the island while on holiday with his family.

Police seeking a toddler missing for 25 years have uncovered several ancient graves during a dig in a field on the Greek island of Kos, where he was last seen, according to reports Thursday.

It is believed that the area may have been an old burial ground.

Police said that the search for Ben Needham will continue despite discovery of the graves which could be 1500 years old.

Police searching for missing toddler Ben Needham have found evidence of “decomposition” at the Kos dig site. A detective inspector revealed that they would be closely examining an area in the olive grove behind the farmhouse where Ben disappeared. It comes as a result of soil samples being sent to the UK, since they are still being examined back at a laboratory in Aberdeen.

British media reports said Thursday that investigators on the island of Kos have evidence of decomposition during a dig to find information about Ben Needham, the toddler who went missing on the island in 1991.
