The harrowing 999 call Jay Slater's frantic mother made to British police after her son vanished in Tenerife can be revealed for the first time.

Jay, from Oswaldtwistle in Lancashire, was found dead in a ravine on July 15 last year after a gruelling 29-day search which sick conspiracy theorists and armchair detectives threatened to derail.

An inquest into the 19-year-old's death in July concluded that he died by accident after tumbling from more than 60ft into a ravine, near the mountainous village of Masca.

The Daily Mail can today reveal the moment Jay's mother, Debbie Duncan, found out her son had disappeared on the Spanish island before she called Lancashire Police to officially report him missing.

Speaking about the moment she received the tragic update, she said: 'I were at work. I got a call from Lucy. She just said "Jay's missing, he didn't come back last night". She just said "I've reported him missing to the police". My legs were just like jelly, I've just gone into panic.'
