Jay Slater, 19, from Oswaldtwistle, Lancashire, has gone missing in Tenerife after attempting an 11-hour walk back to his accommodation following a night out. On 17 June he told his friend Lucy he was lost, needed water, and had only 1% phone battery. His phone then cut off. Former Coronation Street actress Vicky Entwistle, a distant relation, urged prayers for his safe return. His mother Debbie has flown to Tenerife to aid the search efforts, joining local authorities and a specialist mountain rescue team. A Facebook group with over 142,000 members has also been set up to assist. The foreign office is supporting the family. Slater's stepfather described him as 'streetwise' but feared he got lost in the dark, while his mother believes he was disoriented by the unfamiliar area. Emergency services, including firefighters and a police helicopter, are involved in the search.
