The search for missing teenager Jay Slater has been narrowed down to a more specific location after a rescuer has admitted that it is "strange" that the 19-year-old has not been found yet.

Rescue teams are currently searching the Rural de Teno park, a mountainous area with a 2,000-ft ravine where Slater's phone last pinged.

Now, police in Tenerife have honed in on specific buildings in the region to try and locate the missing teenager.

Slater flew from Lancashire to the Canary Islands for a music festival when he disappeared after he went to stay with people he met during a night out on June 16.

During his final call to his friend Lucy Law at 8am local time on Monday, the 19-year-old said his phone had only one per cent battery, he was thirsty and he did not know where he was.

His last location shows the Rural de Teno Park - an area popular among hikers. He has not been seen since and the search and rescue operation is now in its seventh day.

Pictures from the humongous search operation in northern Tenerife today show workers honing in one specific area.

In the middle of the sparse bushland, with a terrain that has been described as "difficult", rescuers have focused their search efforts on two small brick buildings.
