Police have confirmed the death of a 36-year-old man at the T in the Park festival.
Officers said the body of the 36-year-old was found on a campsite at the Strathallan Castle site in Perthshire on Saturday afternoon.
His death is currently being treated as unexplained
A report will be submitted to the procurator fiscal.
Meanwhile police are appealing for information after being made aware of a video showing an assault that is believed to have happened on a campsite at the festival.
Officers are making inquiries into the incident and are appealing for anyone with information to come forward.
The incidents come on the second day of the festival which is taking place at the Strathallan Castle site for the first time this year.
A crowd of about 85,000 is expected today and Sunday.
Concerns were raised about traffic arrangements for the event, and the potential for anti-social behaviour.
Superintendent Colin Brown said: “The vast majority of people have enjoyed themselves and taken our advice and behaved responsibly.
“However, a small number have ignored that advice and have been dealt with. Our advice is simple – look after yourselves and your friends, behave and have a good time.”
Festival organisers have also apologised following delays at pick-up points last night.
Additional measures have been put in place for the end of tonight’s show, including additional stewarding and extra signage, they said.
