Missing teen's friend doing 'everything' to find him
More could be done to help find missing teen Jay Slater, a friend of his has said.
Jay Slater, from Lancashire, went missing in Tenerife on his first holiday with his friends.
Speaking to the BBC's Nick Garnett in Tenerife, Mr Slater's friend Lucy Law said she "hadn't seen one helicopter" since the teen went missing.
The Guardia Civil, the island's police force, told the BBC the search had temporarily moved to the Los Cristianos area in the south on Wednesday due to a potential lead.
But the search returned to Rural de Teno in the north-west of the island, where it continues, it said.
The operation includes police, mountain rescue teams, firefighters and volunteers.
The Guardia Civil said a helicopter launch had been delayed due to the island's weather conditions.
