Jay Slater mystery deepens: Tenerife Airbnb owner opens up on the last time she saw missing teen

The Brit’s phone last pinged in a vast mountainous area around half a mile north of Masca.

Slater was seemingly walking back to the south of the island when he phoned his friend Lucy with just one per cent on his battery.

He also reportedly said he needed a drink of water.

The 19-year-old has not been seen since and a huge search is now underway.

Ophelia, the owner of the holiday rental Casa Abuela Tina, where Slater is understood to have stayed with two people he met on the island after partying at the NRG festival spoke out about his disappearance.

She told Manchester Evening News: "It’s dangerous walking around here, it’s easy to lose yourself.

"He walked up the road when I saw him for the last time.

"He was alone. He was walking normally, though he was fast."

Police have been searching the rural mountainous areas along the north west of the island.

The Civil Guard confirmed on Friday that there had been "no developments" in the search.

Officers were seen looking over the mountains with binoculars.

Mountain rescue teams were also spotted wading through the overgrown hills.

The force confirmed a search was being carried out across the wider Masca area.

Slater’s family, including his mother Debbie, flew out to the Spanish island to assist officers.

She said: "I wouldn't wish this on anybody. I want my baby back. It's a nightmare, an absolute living nightmare."
