Major development in hunt for Jay Slater as police search Tenerife Airbnb: Officers spend two hours inside holiday let where missing teen stayed with two mystery men before disappearing two weeks ago

Spanish police have returned to search the Airbnb where Jay Slater stayed just before he disappeared in Tenerife more than two weeks ago, MailOnline can reveal.

The 19-year-old went back to the remote cottage in the village of Masca with two British men in the early hours of Monday morning after a rave in Playa de las Americas on June 17.

Jay, from Oswaldtwistle, Lancashire, left the £40-a-night two bedroom property called Casa Abuela Tina at 7.30am and posted two pictures from it on Snapchat.

Police on Sunday dramatically called off their search for the British holidaymaker. But now in a new development, two plain-clothes officers were sent to the property at 11am today.

As one of the officers left the property today, he told MailOnline: 'I'm afraid I can't tell you anything about the investigation or our search inside. If you want any details, speak to headquarters, I'm not allowed to talk to you. My colleague and I are from the judicial police and carrying out our own work.'

A local who saw the two officers arrive said: 'They got here around 9am and spent almost two hours inside. They got the key from the owner. I thought it had already been searched but I don't know for sure. It's been taken off the market and not available to book, that's all I know.'

The fact the property has been searched again more than two weeks after Jay was there will raise questions of how the Spanish are handling the investigation.

It comes as: 

• Missing Jay Slater's family are being targeted with fake 'ransom demands' 
• Jay's mother Debbie urges police to keep going with investigation
• Jay Slater volunteers say they WON'T give up search for missing 19-year-old
• Jay's 'disappointed' family meet with Spanish police after search is called off
• Spanish police END hunt for missing teen 14 days after Brit disappeared in Tenerife 
• Jay's father reveals he is 'disappointed' after just six volunteers turn up to join the hunt 

It come after retired former Met Police sergeant David Wettone told MailOnline he 'hoped the property had been secured for evidence as once evidence is lost, it's lost.'

Little is known about the two men other than that they are in their late 30s and early 40s and they have been questioned by Spanish police and allowed to fly back to the UK. 

One is said to go by the nickname Johnny Vegas and one is described as around 6ft, stocky and with short dark hair. He was seen with an orange wristband but little else is known about the other man.

The men were only in Tenerife for a couple of days before travelling back to Luton Airport.

The men had been questioned by Spanish police, but the family were surprised that they have been allowed to return to the UK.

On Saturday, Cipriano Martin, head of the Civil Guard's Greim mountain rescue unit, said: 'Those men have been spoken to and they don't have any relevance whatsoever for the case.'

'I would hope that they have at least secured the Airbnb because if evidence is there then it will need to be gathered.' 

Mr Wettone also suggested the Tenerife authorities should swallow their pride and accept an offer of help from Lancashire police where Jay is from.

He said on Sunday: 'I'm sure the Spanish police kept their details and if need be can go back to them and investigate them with the help of British police.

'I know people are saying these two should have been kept but unless there is any real incriminating evidence it would be hard to keep them in Spain.

'That's why I would start again from the beginning and speak to all the witnesses again, my gut feeling is that many of them may not be telling the truth.

'There are so many inconsistencies in what I am seeing and reading. I think the Spanish police need to take a step back and think 'Why did he go missing where he did and in what circumstances?'

'They seem to be focusing primarily on the fact that they were told he wandered off into the mountain, but we are now almost two weeks in, and nothing has been found up there.

Spanish police have been contacted for comment but have already said previously the case 'remains open and all avenues are being investigated.' 

After the cops officially ended the search for the teenager, Jay's mother, Debbie Duncan, urged police not to 'give up on Jay', according to a family source.

It comes after TV investigator Mark Williams-Thomas revealed that Jay's distraught family are being targeted with fake 'ransom demands'.

Mr Williams-Thomas, who flew out to Tenerife last week to help with the search wrote on X: 'So much fake content has been created in the Jay Slater case - mocked up chat, messages, pic. It's a very different world we live in today with social media and online detectives.

'Overwhelming response from people has been very positive people just wanting to help, even though most have no direct info, just what they have read, seen or think. Also a number of people making vile threats and ransom demands (all checked out and have no credibility).'

In the early stages of the search, Debbie said she thought Jay had been 'taken against his will', while the last person he spoke to - Lucy Mae Law - also echoed kidnapping fears.

Mr Williams-Thomas, who also exposed Jimmy Savile's evil crimes and worked on the Madeline McCann case, has said he has 'been able to speak to important witnesses' and has a 'very detailed picture of Jay's movements' in the lead up to his disappearance.

Jay was last seen at around 8am on June 17 by the owner of an Airbnb he had gone back to with two men after a rave. 

Jay had asked the owner when the next bus to Los Cristianos was and when she said 10am, he decided to set off back to his accommodation on foot for what would have been an 11-hour walk. Search efforts has been focused on a group of small buildings close to where his phone last pinged in the Masca mountains.

The teen's disappearance has left some young British holidaymakers feeling unsafe and being more cautious on Tenerife. 

'I was a little bit more scared coming here and we definitely made sure we had each other's locations before we came which we wouldn't have done before all this happened,' one told Sky News.

Another said: 'I think not less safe but maybe more cautious, more aware. We've all got our locations on... when we booked this holiday we probably wouldn't have even considered the safety measures.'

It comes as Jay's mother Debbie yesterday urged police to keep going with their investigation.

Heartbroken mother Debbie, father Warren, and brother Zak are understood to have spoken with Spanish cops over the phone to make 'sure the police aren't giving up on Jay', according to a family source. 

They have been in constant contact with the police after being left 'blindsided' by Sunday's decision to call off the hunt for the missing 19-year-old apprentice bricklayer after 14 days scouring the mountains in Tenerife.  

Amateur sleuths who have taken over the search for Jay in the police's absence claimed they have discovered a new clue which could help explain what happened to him.

TikTok sleuth and amateur mountaineer Paul Arnott, who has been assisting Jay's family since the police wound down their investigation, told MailOnline a pair of sunglasses similar to the ones Jay was last seen wearing had been found close to where his mobile phone last pinged. 

A family source told The Mirror: 'The family want to be sure the police aren't giving up on Jay. They are in constant contact with them about the case.'

The sunglasses were handed in to the family, which were found by Chris Pennington, 43, originally from Chester and a former British Army reservist who served in Iraq with the Royal Mercian and Lancastrian Yeomanry.

He said he found the sunglasses and believes the area where Jay's phone last pinged suggested someone had thrown it in there.

Mr Pennington who now lives in Tenerife, told MailOnline: 'I've done a bit of hiking and mountaineering and wanted to help out the family.

'They are desperate to find their lad and with my background I thought I could do my bit.

'I parked up near the viewpoint near where the phone last pinged and found them on the ground near some bushes and in the area where they have been searching.

'I don't know if they are Jay's but as a duty of care I picked them up and told the Guardia Civil about them.

'They told me not to touch them if possible and wrap them in paper not plastic and I did and handed them in.

'They also took my DNA and fingerprints as well. It must be awful for the family with the search sacking back and they haven't had any news for two weeks weeks.

'I walked a bit further towards where they said his phone pinged but it was a challenge to get through, it was impossible.

'You would have needed a machete to get through all that undergrowth so this phone pinged from there it's because someone threw it in there.

'The sunglasses were about 50 metres from the road near a tunnel I wanted to search. I saw them glinting in the sun and picked them up.'

Mr Arnott, an adventurer and mountaineer from Flitwick, Bedfordshire, cancelled a charity fundraiser to fly out to Tenerife last week and join the search and rescue operation.

The self-described explorer, who has been sharing clips on TikTok of his own search operation, has been backed by Jay's family, who he claims are 'really proud' of his efforts.

After Spanish officials called off the search, he told MailOnline: 'The police say they have searched everywhere but I'm not happy with that.

'If they had searched everywhere they would have found him, but they haven't and I'm convinced he is on that mountain.

'I've been along ridges and gullies they haven't been down and now I intend to look at two other ravines.

'They say they have searched everywhere but in my opinion that haven't and that's why I am carrying on.'

Mr Arnott also revealed he had refused help from Jay's family and said: 'They are so amazing and lovely. They just want to find Jay and I want to help them.

'They keep offering to pay for my food and accommodation, but I keep telling them no. I don't want anything and I don't want anything from the Go Fund Me site.

'What I would be interested in doing is setting up my own fund to pay for a team from Scotland mountain rescue to come out here.'

Speaking on ITV's This Morning, he said: 'There has been a lot of people around however I've only seen four people actually searching.

'The rest of the people are standing on the side of the road, blocking off paths, trying to stop news reporters going into certain areas.

'The four people that are searching are doing a good job of searching the paths.

'They've gone off-grid a little bit from what I can see but everyone else is just standing about.'

Meanwhile, a family friend told The Times that the Slaters were 'in the dark' about the next steps of the investigation.

It emerged that Spanish authorities say there is 'no current evidence of criminality' in the Jay Slater case.

The female investigating judge who is being kept informed of developments has been told the Civil Guard sees nothing at this stage pointing to Jay being the victim of a crime.

As is standard procedure in Spain, the police force is reporting to a court which has opened a routine judicial investigation and has declined to comment on what it is doing behind the scenes as part of a 'parallel probe' which has continued despite the ending of the visible mountain search.

Mr Williams-Thomas, who worked on the Nicola Bulley case, urged the family to use the £45,000 raised in GoFundMe donations to hire 'experts' to help find him. 

He said: 'Although the police search in the mountains and around Masca has concluded, the police investigation into Jay Slater's disappearance remains ongoing. 

'In regard to our investigation we have been able to speak to important witnesses and now have a very detailed picture of Jays movements over 16 & 17th along with important background information . 

'We still have a number of outstanding actions, but have given the family a preliminary breakdown of findings. 

'In light of the police search ending, I have suggested the family should use the GoFundMe money to continue the search using experts in searching. I would appeal again, if you have any 'direct information' having spoken to Jay or anyone that was with him over night 16/17th and have not yet been in contact please do so .' 

A judicial source, speaking on condition of anonymity as is normal in Spain, said: 'There is no evidence of criminality at this stage in this case.

'That's not to say things won't change because the case remains open and investigations are ongoing. But right now that's the situation.'

Another said: 'This missing persons' case has been judicialised as is normal in Spain and it's been lodged at Court of Instruction Number One in Icod de los Vinos.

'The Civil Guard don't have to tell the judge about everything officers are doing but will be keeping her updated on case progress and of course update her on any significant developments.'

In line with the revelation that the Jay Slater probe is being treated at the moment as a missing person inquiry and not a crime, officials confirmed investigating judge Maria Goya has not declared it 'secret' to protect the judicial proceedings.

An order called in Spanish a 'secreto de sumario' is often slapped on a criminal probe in its infancy, preventing even defence lawyers and prosecuting attorneys from accessing case files.

Such orders also prevent public officials from revealing details of any case files with breaches punishable by heavy fines.

Judges who make their investigations secret when cases are still in their infancy act out of a desire to avoid them being compromised by minimising the risk of leaks.

The judicial source said: 'The Jay Slater case that has been opened at the Icod de los Vinos court is not under any secrecy order.'
