Investigators probing the disappearance of British teenager Jay Slater in Tenerife are pursuing new leads, including the possibility that he may be alive in another part of the island.
Spanish police say there are "several lines of inquiry" still active in the search for the missing 19-year-old.
A source in Tenerife told The Sun that the case remains "very much open" with "all scenarios being kept in mind".
One of the potential leads being explored suggests that Mr Slater could be in a different area of Tenerife, away from the initial search zones.
Investigators have not yet classified the case as "missing feared dead", according to reports.
Mr Slater, an apprentice bricklayer from Lancashire, has been missing for over three weeks. He disappeared on June 16 while on holiday with friends Lucy Mae Law and Brad Hargreaves.
He was last seen leaving an Airbnb in Masca, reportedly to embark on an 11-hour trek through challenging terrain.
The teenager had separated from his friends earlier that night after meeting "new friends" and returning to a different accommodation.
His disappearance was reported by Ms Law hours after he left the rented property.
As the investigation continues, authorities are urging anyone with information to come forward to assist in locating the missing British teen.
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.”
Following two weeks of intensive searching, the official operation to find Mr Slater was suspended on June 30 after authorities found no trace of the missing teenager.
Undeterred, his distraught family pledged to continue the search independently, venturing into the mountainous terrain themselves.
A new search team, led by local hiker Juan Garcia and including Mr Slater’s uncle Glen Duncan, father Warren, and brother Zak, has since been formed.
This group has concentrated their efforts on exploring an area of a gorge, as well as investigating nearby caves, ravines, and slopes in their bid to locate the missing Briton.
