The search and rescue operation on the Greek island of Symi for TV doctor Michael Mosley is carrying on into Sunday and the hunt is becoming more dangerous.
A complicated cave complex known as ‘the abyss’ is now the focus of the search, as there are fresh fears the documentary presenter, 67, could be lost in an ‘endless’ underwater tunnel system.
The TV star set off for a coastal walk on Wednesday while on holiday on the tiny island but did not return, prompting several theories as to his whereabouts.
Initially, it was claimed his tracks were lost, however, stills from CCTV released on Friday appear to show him before he was declared missing having made it to the village of Pedi.
Mosley’s wife Dr Clare Bailey Mosley spoke out on Saturday, saying: ‘It has been three days since Michael left the beach to go for a walk. The longest and most unbearable days for myself and my children.
‘The search is ongoing and our family are so incredibly grateful to the people of Symi, the Greek authorities and the British Consulate who are working tirelessly to help find Michael.
‘We will not lose hope.’
CCTV footage seen by the BBC and released on Saturday also appears to show Mosley walking away from Pedi, and towards the rocky hills.

A representative for Dr Michael Mosley told Metro.co.uk on Thursday: ‘We have no further information yet and are sitting tight hoping for some good news.’
The mayor of the island, Eleftherios Papakalodoukas, has also spoken out, saying it’s ‘impossible’ that he still is where witnesses claim they saw him return from the beach, due to the small size of the area.
It’s now thought Moseley may have walked along a steep uphill concrete road from Pedi which leads to ‘very dangerous’ rocky terrain.
On day four, the search – which has been described as a ‘race against time’ – moved from the sea, and into the mountains.

Dr Mosley went missing on Saint Nikolas Beach
On Friday’s Good Morning Britain, ITV presenter Kate Garraway described the situation as ‘very worrying’ as journalist Niki Kitsantonis, who is based in Greece, shared fears about what might have happened to him.
Speaking on the show, Niki Kitsantonis reported: ‘There are fears he might have slipped.
‘It’s quite rugged terrain in that area, and there are lots of high points you could slip off.
‘The mayor of the island is worried he was perhaps swept away at sea.’
Police have also said there has been ‘no trace of him’.
The searching for Mosley has been arduous and treacherous as temperatures on the tiny island have been reaching 40 degrees Celsius, adding to the fears of his safety.
