Jay Slater's friend Lucy Law shares new pictures of missing teenager after returning to Britain

Lucy was present at the Papagayo nightclub rave where Jay was last seen before vanishing the following morning, after deciding to walk back to his accommodation from an Airbnb he had gone to after the rave with two men.

When the apprentice bricklayer failed to return to the shared accommodation he was staying at with Lucy, she reported him missing, saying that she had last spoken to him on the morning of June 17, when he said that his phone battery was on one per cent.

A huge search effort has since been launched, but the 19-year-old has not yet been found.

Lucy has since returned to the UK and has uploaded new photos of herself alongside her missing pal Jay.

In a collection of five photos posted on her Instagram story highlights - named simply with a blue heart emoji - Jay and Lucy pose together alongside other friends too.

In the first picture the two teenagers pose next to each other, while the second story includes a collage of three different images, where two of them depict Jay and Lucy sitting at a booth.

LATEST DEVELOPMENTS:

• Jay Slater 'could be alive in different part of Tenerife' police claim as they pursue three leads
  
• Jay Slater's family joined in search by Essex politician who has climbed Mount Kilimanjaro

Similarly, the remaining three images also feature Jay and Lucy, alongside other friends - with the setting for two being in a nightclub while the third is in a kitchen.

This comes as investigators in Spain have claimed Jay could still be alive.

Spanish police have maintained the case for the missing 19-year-old is "very much open" with "all scenarios" being kept in mind.

A source told The Sun: "Even though the ground search for Jay is over, the investigation into where he might be still remains very much open.

"One line of inquiry is a theory that Jay might even be in a different part of Tenerife and still alive. All scenarios are being kept in mind.

"The case is very much open because there are still a number of unanswered questions which officers must find answers to.

"They are convinced someone, somewhere knows what happened to Jay or knows where is now is, and that’s what they are working towards trying to establish as quickly as they can."
