Dr Michael Mosley CCTV sparks long shot 'possibility' as it rules out 'fall' theory

CCTV of TV doctor Michael Mosley has been released - showing that he had made it back to the town where he was staying. The surveillance footage shows Dr Mosley on the main road of Pedi at 13.50pm on Wednesday afternoon, approximately 20 minutes after he is believed to have embarked on a coastal hike from a nearby beach which locals described as taking around 20 minutes.

It had been speculated by Greek officials that the healthcare expert may have come to harm on the coastal walk, either collapsing in the 35C heat or falling from a cliff during his walk. But the CCTV footage disseminated by local site MEGA after being retrieved by police officers shows Dr Mosley back in Pedi on the island of Symi, where the presenter was holidaying with his wife, Dr Clare Bailey.

It has now led officials to consider the long shot possibility that he may have left the island, but there is no evidence of travel under his name. Police, firefighters, the coast guard, sniffer dogs, helicopters and drones have all been called in to search for the 67-year-old.

But so far there has been no sighting of the star. The hunt for Mosley is centred around the stretch from Agios Nikolaos to Symi's main town, following his reported walk route.

Symi Mayor Eleftherios Papakalodoukas told the BBC last night that they thought it was 'impossible' for Dr Mosley to still be on the island. He said: “It is a very small, controlled area, full of people. So, if something happened to him there, we would have found him by now.”

The UK's Foreign Office has confirmed they're liaising with Greek officials regarding the search. Mosley, a familiar face on British TV and radio, also pens a column for the Daily Mail.

Internationally, he's recognised for his 2013 publication "The Fast Diet," co-written with Mimi Spencer, which introduced the "5:2 diet" concept where people eat normally for five days a week and then restrict calories for two days to achieve rapid weight loss.

Mosley and his spouse Clare Bailey Mosley, a fellow doctor, author, and health columnist, have four children.
