Police are investigating claims that a teenage girl was raped at a T in the Park campsite.
The allegeed attack on an 18-year-old girl is said to have happened after a night in the festival's Slam Tent at the Strathallan campsite.
Officers confirmed they are investigating claims of a rape on Thursday night.
A Police Scotland spokesman said: "Police are making enquiries into a report of a rape of an 18-year-old female on Thursday evening.
“Our enquiries are ongoing."
Festival-goer Sean Gillies, 29, of Edinburgh, said: “The festival should be a place for people to come and be safe and have a good time. For a woman to be attacked is just terrible. It’s crazy that something like this would happen.
Rachel Jackson, 28, told the Sun: “I noticed the police were examining a tent in the campsite. One of the girls told me a young girl had been attacked.
“The police were there for quite a while. It’s terrible that this has happened.”
The shocking claims come shortly after the death of two teenagers at the popular music festival which sees over 80,000 revellers pass through its doors.
17-year-old Megan Bell, from North England, took ill on Thursday night in the Slam Tent and was taken to the festival's medical centre but died shortly after.
Scottish teenager Peter MacCallum, 17, of Lochgilphead, Argyll, was found unconscious in his tent and pronounced dead at around 5am.
It is believed their deaths were related to drugs but not linked to one another.
T in the Park organisers issued further drug warnings to revellers following the death of the two teenagers.
They tweeted: “Drugs are illegal and dangerous. If you see anything suspicious, report it to a steward or police officer.
“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. If you or your friends feel unwell, seek help immediately from festival staff.”
Festival boss Geoff Ellis added: “There are serious medical risks of taking drugs and we do various things to try to stop them being brought in.
“We have always had amnesty bins but this year we’ve put some inside the festival and campsites.”
He also confirmed T in the Park would continue for the forseeable future after music fans called for its closure following the tragic deaths on Thursday.
