One of the 12 boys saved during the Thai cave rescue in 2018, has died in the UK.

Duangpetch Promthep enrolled in the Brooke House College Football Academy in Leicester late last year when he was 17.

His cause of death is still unclear but he was said to have sustained a head injury.

Promthep was the captain of the Thai boys' football team, The Wild Boars, which was trapped in a cave along with their coach for two weeks while exploring the Tham Luang cave complex in Chiang Rai province.

Some of his teammates from the cave rescue have also shared the news of his death on social media.

The temple posted condolences to Promthep - also known as Dom - on Facebook on Wednesday. "May Dom's soul rest in peace," said the post, which was accompanied by pictures of the football team with monks.

Zico Foundation, a Thai non-profit that had helped Promthep win a scholarship to study in England, also expressed condolences on Facebook.

The Wild Boars football team became trapped while exploring the vast cave complex in 2018 when heavy rainfall flooded the exit.

Duangpetch was 13 at the time, while his teammates were aged between 11 and 16.

They were eventually rescued nine days later by a team of nearly 100 divers, including british cavers Rick Stanton and John Volanthen. During their rescue the team were sedated with the drug ketamine. A former Navy SEAL diver Saman Kunan died during the rescue. 

The dramatic rescue made headlines around the world, and various films and books were later made to retell the story, including a six-episode series released by Netflix.
