A teenager who died in a camp site at the Reading Festival has been named.
Paramedics, on-site medical staff and Kieran Anthony Griffin's friends all battled to revive him after he stopped breathing at about 0500 BST on Monday.
The 18-year-old was pronounced dead on arrival at the Royal Berkshire Hospital.
Mr Griffin's parents travelled down from their home in Leighton Buzzard, Bedfordshire, to Reading to formally identify his body.
A Thames Valley spokeswoman said: "Police are currently working with festival organisers and the coroner's office to investigate the unexplained death at the Reading Festival site.
"Officers were called following reports that a man in the camp site area off Cow Lane appeared to have stopped breathing."
Police are not treating the death as suspicious.
The result of a toxicology report, following a post-mortem examination conducted on Tuesday, is expected to take about a week, said police.
Inspector John Relph, who has been overseeing the running of the festival,
said: "The tragic events of this morning's sudden death have dampened things
and our sympathies and thoughts are with the family of the boy who died.
"The festival has run smoothly this year with a small number of minor public
disorder and violence incidents, which is expected with a crowd of more than
60,000 people on one site."
