New photos have been released of emergency crews working on the ongoing search for Jay Slater.
The 19-year-old has been missing in Tenerife since Monday, with his increasingly desperate best friend begging for British police to get involved.
The photos were shared on Facebook by the Bomberos Voluntarios de Santiago del Teide - volunteer firemen in the area. Their post read: "On Tuesday morning, at 2:17 a.m. we are given a notice to search for the missing young man in Masca.
"A vehicle and personnel were dispatched to the site and together with firefighters based on Icod and officers from the civil guard of the mountain rescue team carried out a search in the area of the Ilda Mirador.

Jay Slater was reported missing by his friends on the Spanish island on Monday morning (June 17). The 19-year-old, from Oswaldtwistle in Lancashire, disappeared after going to stay in an area on the north of the island with people he had met on a night out following the NRG music festival.
His friend Lucy last heard from him at around 8am, when he told her needed a drink of water and that he was trying to walk back to their accommodation after missing a bus - a journey expected to take around 11 hours on foot. Since then, a huge search has been ongoing where his phone's location was last tracked.
Emergency crews have been scouring the area in the Rural de Teno Park near the village of Masca, close to a route which is popular with hikers. As of this morning (Thursday), Jay remains missing.
Last night, after flying out to Tenerife, Jay's mum Debbie Duncan, said she was "living in a nightmare". Speaking to ITV News, she said: "It’s just a nightmare, it’s an absolute living nightmare. I wouldn’t wish this on anybody. I just want my baby back.
"Please just anybody who can help – look for him. It’s a massive area up there. He’s out there somewhere or somebody knows where he is."
Jay's friend Lucy has now also set up a Go Fund Me page to raise funds to pay for his family and friends to stay in Tenerife to assist the search. A Go Fund Me spokesperson confirmed the page has been 'verified', with more than £13,000 raised so far.
Debbie also revealed that she had been sent a terrifying Snapchat message which said 'kiss goodbye to your boy', and claimed that Jay owed the sender 'lots of money'.
"I got a Snapchat about ten minutes after I got off the plane saying ‘Kiss goodbye to your boy, you’re never going to see him again, he owes me a lot of money.’ which I passed on to police with the number it came from because I had my wits about me at the time and got my eldest son Zac to take a screen grab before it disappeared," she said.
Tenerife told to get rid of UK tourists in popular item on beach amid tensionsWhile authorities have been combing the dry hills around Masca and the Parque Rural de Teno area, Lucy has said she is sure he has been taken and is being held against his will.
Lucy told MailOnline: "It's been three days now since he was last seen and the more time goes on the more I'm sure he has been taken. At first I wasn't so sure but now I'm convinced. He is not stupid - if he left the house on his own he would have walked to the road and then tried to flag a car down or stop someone for help.
"The last time we heard from him it was around 9am so the place where he would have been walking would have had hikers and holidaymakers. The more time passes and he has not been seen then the more we are convinced he has been taken by someone and is being held against his will."
A worker at the Masca visitor centre, which manages reservations for nearby hikes, said the region was remote and people did often get lost there. "If you get off the trails that are official it can be risky as you may not know where you are walking. Usually only locals go there because they know the ways - but if you’re not from here it can be dangerous," she said.
