Jay Slater's father calls for Interpol to get involved in the search for his teenage son after claiming the Spanish police probe into his son's disappearance 'stinks'
Missing raver Jay Slater's father has called for Interpol to get involved in the search for his son who has now been missing for three weeks on the Spanish island of Tenerife.
Desperate Warren Slater, 54, spoke out after spending more than six hours searching a mountainside with Jay's brother Zak, 24, in searing 25C temperatures as they continued their desperate hunt for him.
The 19-year-old apprentice bricklayer has not been seen since he went to a remote AirBnB at Masca, an hour from the party resort of Playa de las Americas on June 17, in the Parque Rural de Teno with two men.
Police and mountain rescue teams using dogs, drones and a helicopter spent 13 days looking for him before calling the search off on June 30 and have dismissed the men as 'irrelevant'.
Warren said: 'We need to, as a full family, do a proper press conference and ask the British authorities to help. He's a British citizen. Get Interpol involved.
'It's just us. I haven't got a team. We need a team to come over here and find out for us what the police are doing and what we need to do.

'Our hands are tied over here, we need experts. How long can you stay here for?
'It'll take an army 10 years to cover all this. I'd employ a team of Gurkhas.'
Last week MailOnline identified one of the men who drove Jay back to the Airbnb as convicted drug dealer Ayub Qassim, 31, but he has insisted the youngster 'arrived alive and left alive'.
Warren and Zak have been focusing their search on an area of the valley where Jay's phone last pinged and from where he sent his location to friend Lucy Mae Law, 19.
She said the last time she heard from him was at 8.50am on June 17 and he said 'his phone was down to one per cent, he was lost and thirsty' before the line went.
Warren said: 'I've been through 80% of that valley, so we went further along.
'We've driven and we've walked down the path at the next village, up the mountain there's a viewpoint that looks down, you can either follow the road, but we didn't, we parked up and walked down.'
Police say Jay walked up the hill from the village of Masca in the wrong direction, at 8.15am, after being told there was no bus back to his Paloma Beach hotel in Los Cristianos until 10am.
Warren, pictured during the search, said: 'It's the fourth time I've done this. It was hard, I nearly put my eye out. Tell me where I look, I can only go off the last sighting'

Missing Jay posted a final picture at 7.30am on Snapchat from the house of 'two English lads' an hour before phoning his friend Lucy
They believe he then left the road and took a remote path down into the desolate valley in the mistaken belief it was a short cut back.
But sceptical Warren said: 'It doesn't make sense, he's either hid himself, but why would he hide himself? Or he's just ….?
'We've done the valley where his ping was, we've gone up the road to a vantage point, there's cliffs there and there's a valley and a village there.
'All I'm thinking is common sense, would you try and walk through there. Where we've been today you can see there's a hiker's path with proper stones.
'We've gone straight down, and you end up in the village.'
Warren described how they had also searched a derelict stone cottage halfway down the track where there were water bottles, empty tea bag boxes and women's clothes.
He said: 'I'd go into the first building you see. Ideal spot for shelter is that little cave isn't it, get a bit of shade, you're hung over, get your head down in there.
'The police are convinced that's where his last ping were. From the Airbnb, he's a fit lad, 25 minutes you can get to the top, to where the cafe is.

'If he's followed the road and been where we've been today, it's took him an hour and a half.
'Dozens of cars would have gone past him. We got here at 9am and the 10am bus passed us. And it would have passed him.
'I've been up here three weeks and I've never seen as many cars.
'We've been on two wild goose chases yesterday to abandoned buildings.'
Spanish police have said the investigation remains 'open' and they are 'pursuing all avenues' but refuse to disclose if they believe there as any third-party criminal involvement.
