Police are investigating the deaths of a man and a woman at the T in the Park music festival in Perthshire.
The deaths are being treated separately and are at this stage unexplained, Police Scotland said.
Campers began arriving on Thursday for the three-day event at Strathallan Castle, which will see The Stone Roses headline on Friday.
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."
T in the Park is Scotland's biggest music festival, regularly attracting more than 80,000 revellers over the weekend.
This year marks the second time the event has been staged at Strathallan after moving from Balado in Kinross-shire in 2015.
Jamie XX, Disclosure and Courteeners are also scheduled to perform on Friday, before Calvin Harris and the Red Hot Chili Peppers headline on Saturday and Sunday.
