A man and a woman have died at T in the Park music festival. 

Police are conducting separate investigations into the death of a male and the death of a female at Strathallan Castle in Perthshire. 

The deaths are being treated as unexplained.

It is believed the man and woman were both discovered in the campsite in the early hours of Friday morning.

Police say they will not rule out drugs as a cause of death. 

Unconfirmed reports say they are both teenagers.

A Police spokesperson 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."

"We are unable to comment further at this stage."

The festival doors to the campsite opened yesterday ahead of the opening of the music arena today. 

More than 80,000 people are expected to attend the three-day event.

Last year a 36-year-old man was found dead in the toilets at the Strathallan Castle site in Auchterarder.

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."

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."

T in the Park organisers released a statement warning revellers not to take drugs.

On the official Twitter page for the festival, the statement warned those attending to avoid drugs and not to "risk it".

It said: "Don't risk it - you don't know what's in drugs, where they came from, or how you'll react to them, steer clear. 

"Be vigilant - drugs are illegal and dangerous. If you spot anything suspicious report it to stewards or a police officer. 

"Don't delay - if you or your friends feel unwell, seek help immediately from any festival staff." 

Police Scotland have so far said the two deaths are being treated as "unexplained". 

But a police source said the deaths were "possibly" linked to drugs. He added: "We can't rule anything out or anything in."
