Haunting surveillance footage captured well-known British television presenter Dr. Michael Mosley just before he vanished during a vacation in Greece.

The 67-year-old appeared to have grabbed an umbrella and gone for a walk along the coast on the island of Symi on Wednesday morning, the images showed.

One frame showed the physician walking past a cafe.

Mosley’s wife, Dr. Claire Bailey, reported him missing at 7: 30 p.m. that day when he failed to return from St. Nikolas Beach, the Telegraph reported.

The doctor was out on the walk without his phone – which made it nearly impossible for local authorities to track him, the outlet added.

“We have no further information yet and are sitting tight hoping for some good news,” Mosley’s rep told London’s Metro on Friday.

On Friday, coast guard officers, divers, and even specialist dogs were seen scouring the small island in hope of finding the popular physician and columnist.

Mosley’s three children also flew out to Symi, where they planned to join the search, the Telegraph said.

 “There are fears he might have slipped,” Greek journalist Niki Kitsantonis told Good Morning Britain.
