A teenager has been found dead in his tent at the Carling music festival in Leeds.

The 19-year-old, from Derbyshire, was discovered by friends at about 1045 BST on Sunday.

Police said the man - who is believed to have had a history of congenital heart problems - had been drinking during the night.

Chief Inspector Tom McSorley, of West Yorkshire Police, said: "We are not treating this incident as suspicious."

The identity of the dead man has not been released.

He was among 50,000 music fans attending the festival at the Temple Newsam site.

The festival, which includes acts such as The Strokes, Pulp and Prodigy, is also being staged in Reading with many of the main acts appearing at both venues.
