Members of missing teenager Jay Slater's family have been spotted in a new area today as their search for the 19-year-old continues.

Jay, from Oswaldtwistle, Lancashire, disappeared on the Spanish island on the morning of June 17. Despite a huge search from Spanish authorities and the help of TV detective Mark Williams-Thomas, he is still yet to be found.

On Monday (July 8), new pictures show Jay's brother Zak and dad Warren in Santiago del Teide, a mountain village on the outskirts of the Teno Rural Park. It comes as the pair widen their own search boundaries on the three week anniversary of his disappearance.

Earlier they had searched higher in the mountains in the Los Carrizales valley. His last known location was the Rural de Teno Park in the north of the Canary Island - where much of the search has been focused so far.

His last known contact was on the morning of Monday, June 17, as he tried to return to the tourist hotspot of Los Cristianos, where he had been staying with friends Lucy Law and Brad Hargreaves.

On Sunday, Warren told of how the search for his teenage son is 'like a riddle' he has no answer to. It comes after he joined a team of 10 volunteers on Saturday to scour the hostile landscape in which Jay went missing.

He told the Mirror: "Tell me where I look, I can only go off the last sighting, the woman in that restaurant saw him going the wrong way. Which human being lets a young boy go the wrong way? Everything stinks. It’s just a riddle and I don’t know the answer."

He also questioned why Spanish police had ruled the two men Jay went back to the Airbnb with on the night he went missing out so quickly.

He said: “My starting position, I’ve said this from day one, ask the two men who’ve taken him. And then start from there.

"If you and me in England had taken a young girl to the Lake District, do you think they would have let us go back to Spain? We’re going round and round in circles. The Spanish police, you can’t go screaming and shouting at them because they don’t do anything.

“If you start screaming and shouting they won’t do anything even more. If they want to go and search a house they have to go to court first.”

Last week, Spanish police called off their search for Jay Slater following two weeks of gruelling activity. A number of volunteers remain in Tenerife, alongside his family, to keep looking for the missing teen.
