Attempt to find British teenager now in its second week as groundless theories circulate about his disappearance

As the search for Jay Slater, the British teenager who went missing while on holiday in Tenerife, enters its second week Spanish rescuers continue to comb the rugged mountain terrain where he was last seen for clues.

Staff and volunteers from the local police, fire brigade and civil defence force have been using dogs, drones and helicopters to hunt for the 19-year-old apprentice bricklayer from Lancashire.

Debbie Duncan, mother of Jay Slater, says it is right that search should be intensified for 19-year-old

The mother of Jay Slater, the 19-year-old apprentice bricklayer who is missing from Tenerife, has said she believes that Spanish police have intensified their search for him, as the hunt enters its sixth day.

Debbie Duncan told the Guardian she spent eight hours in a police station on Friday, as police outlined their detailed plans to search for the missing teenager from Lancashire. “I think it’s been stepped up,” she said, which she described as “too right”.
