A missing persons expert has delivered his verdict on the "most likely outcome" for missing Briton, Jay Slater.

The search has now entered day six after the 19-year-old mysteriously disappeared in Tenerife earlier in the week.

The young boy disappeared when attempting to walk back to his accommodation after missing a bus.

He was last heard of when he phoned his friend Lucy Law and said that he was lost and had one per cent charge left on his phone.

Speaking to GB News missing persons expert Charlie Hedges said: "Well, the search must continue. We should always keep hope in the eventuality that we are going to find him.

"But after six days missing in this sort of terrain, it is looking bleak. But as I say, we must also keep our minds open to other options so that we are pursuing all options and all sorts of different outcomes."

The expert also compared the case to that of the TV doctor Michael Moseley, who was found dead after he went missing on the Greek island of Symi.

Hedges said: "There are similarities. But there have been a few other cases in Greece recently where people have wandered off and have come to an unfortunate end.

"So, yes, I think there's a bit of a similarity between all of those cases."

He added: "Yes. I mean, it's very easy to wander off and get caught out by difficult terrain.

"The high temperature, if you haven't got sufficient water and all these things can have a significant impact on the body's ability to deal with the terrain.

"Plus, there's a high risk of tripping and falling in this rugged area. So they all contribute together."

Slater, from Oswaldtwistle, Lancashire, was last heard from on Monday as he told a friend he planned to walk to his accommodation after missing a bus, a journey expected to take around 11 hours on foot.

His friend Lucy said that Slater had gone to stay with people he had met on holiday while on a night out.

She said she received a call from the 19-year-old at around 8.15 am on Monday after he missed the bus and was trying to walk back to warn that he was lost and only had one per cent battery on his phone.

His last location is shown as the Rural de Reno park, a mountainous area popular with hikers.
