New search for Jay Slater underway in Tenerife BBC News

A new search is under way in Tenerife for missing British teenager Jay Slater following calls from Spanish police for volunteer help.

On Friday the Guardia Civil asked voluntary organisations and members of the public with expertise in difficult conditions to come to northern Tenerife.

Dozens of experienced local firefighters, police and mountain rangers are leading the search.

Authorities had hoped the operation would be a "massive search" but less than 12 members of the public had arrived at the meeting point before it began.

The 19-year-old has not been heard from since the morning of 17 June, after he told a friend he was lost in the mountains and had 1% battery on his phone.
