Officers from Guardia Civil in Tenerife have narrowed the search area for missing British teen Jay Slater to specific structures near where his phone last pinged.
After days of searching in Masca and its surroundings, efforts now concentrate on the Rural de Teno Park.
19-year-old Slater, who disappeared last Monday after the NRG music festival, was last heard from whilst trying to return to his holiday accommodation.
