A teenager has collapsed at a 16-hour rave in Spain and later died during a holiday he booked with pals to celebrate the end of his A-levels.

Tragic Alex Masterton, 19, passed out at the Barcelona club on Saturday night.

He was treated by local ambulance crews before being taken to a nearby hospital, where he died.

Alex, from Grimsby, had travelled to the seaside town of Salou with a group of friends and was ending his week-long holiday at the Elrow 7th anniversary event.

Described as “a 360-degree day time event with Elrow's trademark of surreal madness” by the organisers, it includes three music stages, art installations, food experiences, market stalls and immersive decoration.

A student at King Edward Grammar School, Alex had been due to study Biomedical Sciences at Newcastle University in September.

Headteacher James Lascelles told the Grimsby Telegraph: “All of the staff and pupils at King Edward who knew and taught Alex were shocked and deeply saddened to hear of his passing at such a young age.

"Alex has been at King Edward’s since Year 7 and had just completed his final exams with us in Year 13 in preparation for a degree in Biomedical Sciences at Newcastle University.

"During his time with us Alex had grown and matured into a lovely lad with real personality. The Sixth Form Team and his teachers were fond of his positivity, warm smile and his sharp sense of humour.

"His loss will be deeply felt by those who taught him and amongst his friendship groups at King Edward’s.

"Our thoughts and prayers go out to his parents, family and friends and our pastoral team at King Edward’s, supported by the team at St James’ Church stand ready to provide all and any assistance to his family and friends at this dreadful time."

Speaking of the event to mixmag magazine, which crowned Elrow its club of the year in 2016, CEO and founder Juanito Arnau told mixmag magazine: “After seven years offering shows all over the world, at last we've found the perfect spot to put on the most creative show ever done by the Arnau family in all their long history.

"For the first time we're joining forces with some of the most crazily, imaginative people we've met around the world, from countries such as Brazil, Portugal, the United States, South Africa, Holland and the UK.

"Get ready to experience something you've never ever seen before.”

Temperatures in the area had peaked at a record 47 degrees Centigrade during the week.

A Foreign and Commonwealth Office spokesman said: “Our staff are supporting the family of a British man who has died in Barcelona. They have offered advice on bereavement abroad and repatriation.”

His family have been informed by Lincolnshire Police.
