Tragic teenage festival-goer Anya Buckley had MDMA, cocaine and ketamine in her system when she died, a coroner heard.
An inquest into the death of the 17-year-old from Oldham opened on Thursday.
The teenager died following a suspected drugs overdose at Leeds Festival in the early hours of the morning of Saturday, August 24.
She suffered a cardiac arrest at the festival site at Bramham Park.
Toxicology results provided to Kevin McLoughlin, senior coroner for West Yorkshire, showed that Anya had a combination of MDMA, ketamine and cocaine in her body at the time of her death.
Opening the inquest at Wakefield Coroners Court, Mr McLoughlin said: “On August 23, Anya Buckley, aged 17, travelled with friends from the Oldham area to attend Leeds festival.
“At 01.17am on Saturday, August 24, she was taken ill and was taken for a medical assessment.
“She did not improve and suffered a cardiac arrest and was pronounced deceased.
“Tests show she had MDMA, cocaine and ketamine in her system.
“A police investigation is currently underway.
“I would like to offer my heartfelt sympathy to her family.”
The inquest was adjourned after being opened.
A date for a full hearing will be fixed in due course.
Following Anya’s death, her heartbroken friends paid tribute to her describing her as a ‘beautiful angel’.
In an emotional post on Twitter, Alexandra Lovatt wrote: “Anya I would do anything just to speak to you one last time.
“I don’t understand how something so horrible could happen to the most kindest and loving person I’ve met.
“I’m so grateful I had you in my life, so many people loved you and I wish you could see that. Fly high Anya. Love you forever and always. RIP beautiful.”
Jessica McDermott also tweeted about her friend writing: “Rest in peace, my beautiful angel. What I would do to see you one last time.”
While Charley Ward added: “Rest in peace gorgeous girl. I can’t even describe how heartbroken I am right now. A precious life taken too soon.”
Festival Republic director Melvin Benn said: “To say we are deeply saddened about this tragedy is an understatement.
“The West Yorkshire Police have taken action against those that may have supplied the drugs, and we will continue to work with them as usual.”
A 17-year-old boy, also from Oldham, was arrested on suspicion of supplying controlled drugs but was released under investigation.
