Everything Jay Slater's friend Lucy Law has done to try to find missing teen

Ever since Jay Slater went missing in Tenerife five days ago, his friend Lucy Law has worked tirelessly to try to find him. She was the last person to speak to the 19-year-old on the phone before his battery ran out and the call was cut off.

Jay had travelled to Tenerife for the three-day NRG music festival. During the call, he told Lucy he 'didn't know where he was' and needed water after travelling to a fellow partygoer's property.

He had stayed in Rural de Teno Park with twofestivalgoers he met the day before he went missing. The area is a 40-minute drive - or 11-hour walk - from his Playa de las Americas holiday apartment. Jay, of Oswaldtwistle, Lancashire, told Lucy he intended to make the journey back by foot but he has not been seen since.

Lucy told Manchester Evening News: "He's gone on a night out, he's gone to a friend's house, someone he has met on holiday. One of the people he has met has hired a car out of here so he's driven them back to his apartment and Jay has gone there not realising how far away it is.

"In the morning he's set off walking, using his maps on his phone and ended up in the middle of mountains with nothing around." Lucy later told Sky News her missing friend had 'cut his leg on a cactus' as he attempted to walk along a remote path.

Lucy was able to track down the house visited by Jay after the festival by tracing a snapchat picture, The Mirror reports. An American woman drove Lucy up into the rocky terrain where they found a house which matched the photo.

The people inside told her Jay had gone out for a cigarette before heading back inside to tell them he wanted to go home, it was reported. "They told me he'd spoken to the next-door neighbours and they'd told him there was a bus every ten minutes back down to Los Cristianos," Lucy said.

"The bus stop was right next to the house. So obviously if he'd gone to get the bus he wouldn't have got lost because it [the stop] was visible from the front door."

The last Snapchat picture shared by Jay before he vanished shows a hand holding a cigarette at a property in the Buenavista del Norte area at 7.30am on Monday, 45 minutes before his 8.15am call to Lucy.

She added: "I can't understand why he would come out of the house and then decide he was going to walk. I think he maybe set off walking with battery and had not realised how far the walk actually is."

Speaking about the local police, she told ITV : "I got the phone put down on me by the Spanish authorities so I went to speak to them in person. I've had my phone stolen before, and they gave me the same slip of paper.

"They told me I'd get a call within 48 hours, but obviously the 48 hours after a person goes missing can be the most crucial. I've tried to report a 19-year-old is missing with no phone, no water, he's never been in this area. There definitely needed to be more urgency."

She added: "We need British police here. I just want to find my mate. He's been missing three days. It’s not looking good now. We feel it's down to us to find him and we're doing more than the police.

"The police here don't speak English and don't even have a translator after three days. I feel they're fobbing me off. They're still asking me the same questions as when I first reported Jay missing."

Lucy continued: "The two boys he was last with have left the country. They need to be questioned by British police."

Another friend of Jay said: "We've been told the two guys Jay was last with are from Luton. One is known by the nickname Johnny Vegas. We're sure they know something.

"The island police say they have copies of their passports, but we've been told they flew back to Gatwick yesterday. We drove all round the ravine yesterday for 12 hours and we're getting out shouting and screaming Jay's name, but we couldn't find anything."
