Jay Slater's dad has demanded Interpol step in to scour the area where the missing 19-year-old vanished. Missing Jay's dad Warren has called on British cops to launch their own investigation into his son's disappearance- in Tenerife.

A distraught Warren is with Jay's older brother Zak scouring Tenerife for any trace of Jay. Warren has been in Tenerife for weeks searching for his missing son in the wake of the apprentice bricklayer vanishing in mid-June.

Warren said: "As a family, we need to ask the British authorities to help. He's a British citizen. Get Interpol involved. At the moment, 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." Warren said the family are now expanding their search area and said: "I’ve been through 80 per cent of the valley, so we went further along. We’ve done the valley where his phone pinged. We’ve been on two wild goose chases to abandoned buildings.

"Now, we’ve gone up the road to a vantage point, there’s cliffs there and there’s a valley and a village there. Where we’ve been today you can see there’s a hikers path with proper stones. We’ve gone straight down and you end up in the village."

Shortly before his disappearance, Jay called friend Lucy Law, who he was staying with on the south of the island, to warn her that he was trying to get back to their hotel, however his phone was on one per cent battery. She claimed he said he was 'thirsty' and had no idea where he was.

The young woman also said her friend mentioned being cut by a cactus.
