Police are investigating the deaths of two teenagers at the T in the Park music festival in Perthshire.

Scotland’s biggest music event got under way on Friday with the news that a male and female had died.

The deaths are being treated separately and are at this stage unexplained, Police Scotland said.

Reports suggest the deaths are drug-related, but this has not been confirmed by police.

The festival’s official Twitter account has issued a warning to festival goers regarding drugs.

It read:

Festival director Geoff Ellis said: “We are shocked and saddened by today’s news and our thoughts are with the families and friends at this time.

“We are offering our full support and assistance.”

T in the Park

Campers began arriving on Thursday for the three-day event at Strathallan Castle, which will see The Stone Roses headline on Friday evening.

More than 80,000 revellers are expected over the weekend with a line-up which also includes Calvin Harris and Red Hot Chili Peppers.

T in the Park is being staged at Strathallan for the second time after moving from Balado in Kinross-shire in 2015.

Last year, a 36-year-old man from the north of England was found dead at the campsite. There were no suspicious circumstances.

A police statement said: “Police Scotland can confirm we are investigating reports of the death of a female and the separate death of a male at T in the Park.

“The deaths are unexplained at this time and work is ongoing to establish the exact circumstances surrounding both.”

Liz Smith, Scottish Conservative MSP for Mid Scotland and Fife, said: “This is tragic news and I am sure I echo the sentiments of everyone when we send condolences to the families involved and, indeed, to the organisers of T in the Park who have worked hard this year to overcome last year’s concerns about public safety.

“Clearly, an investigation now has to take place and I hope this will be undertaken as quickly as possible. It is essential that police establish exactly what happened and why.”
