A 17-year-old has died after taking drugs at Leeds Festival, leading two other teenagers to be arrested on suspicion of drugs offences.
The boy was taken to hospital at 4.45pm on Saturday after taking drugs, and was from the Greater Manchester area, West Yorkshire Police said.
Police said he underwent emergency treatment but was pronounced dead shortly after midnight.
Two 17-year-old males have now been arrested in the Greater Manchester area and are being questioned by police.
Chief Superintendent Keith Gilert, Leeds Festival's police commander, said: "Our thoughts are naturally with the family of the young man at this time.
"They were made aware of the incident by officers as soon as possible and were assisted to attend the hospital as quickly as possible. We will continue to support them through this difficult time."
"We are currently investigating the death and how he obtained the substance he took."
"Two males, aged 17, have been arrested in the Greater Manchester area on suspicion of drugs offences and are currently in custody.
"At this time the indications are that the man consumed drugs immediately before before he collapsed."
