Michael Mosley's final moments before his death revealed as he attempted to 'follow routine advice'

Two days after the body of British television presenter Michael Mosley was discovered by Greek police following a three-day-long search of the island of Symi, his final few moments have been revealed.

The 67-year-old doctor and health expert - famed primarily for his appearances on TV programmes such as The One Show - was last seen on Wednesday (5 June) after heading for a walk along St Nicholas beach.

Michael had been on holiday with his wife Dr Clare Mosley at the time, leaving his phone on the beach with her before setting off on a walk across the island.

After he failed to return home, she alerted police, after which a search mission quickly began.

In the days that followed, police, firefighters with drones, Greek Red Cross workers, divers, a search dog and a helicopter all joined in the efforts to locate Mosley.

CCTV recovered on Saturday showed the father-of-three walking past a beach bar at the Agia Marina, making his way down a rocky slope close to a fence before he falls out of view.

Tragically, however, the doctor's body was found beneath a fence that runs around a bar on the same coastal area the following morning.

Police arrived at the location 20 minutes later, before firefighters turned up to the scene just after 2pm to take the body away from the island on a boat.

Michael's wife later confirmed the identity body, describing her loss as 'devastating' whilst thanking the authorities in a heartbreaking statement.

"Michael was an adventurous man, it’s part of what made him so special," she told PA News.

It was initially believed that the TV doctor had made an 'incredible climb, took the wrong route and collapsed where he couldn’t be easily seen' by emergency search teams.

Earlier today, another set of CCTV footage was released by Greek news outlet Mega, which sees the TV star walking with his umbrella in hand as he passed a beachside property, recorded just two hours after he is believed to have passed away.

Now, police on the island reportedly believe that Michael died of heat exhaustion after losing consciousness whilst walking in 40+ degree temperatures.

According to The Telegraph, an initial examination of the doctor's body, combined with CCTV footage and forensic evidence from the scene all contribute to the idea that he'd died of natural causes.

In turn, the outlet alleges that police have ruled out foul play or criminality.

Symi police commander Dimos Kotsidaras also told the outlet that a coroner's report confirmed that Michael had sat down before losing consciousness in the heat, just yards away from safety.

The doctor was found lying on his back with his legs in the air, suggesting he'd attempt to follow globally-recognised advice that this can help to prevent fainting.
