THE two-week clean-up operation following the 20th anniversary of Scotland's biggest music festival has begun.

Festival headliners The Killers brought the festival to an end the main stage of T in the Park on Sunday.

Over three days more than 200 acts performed at Balado, Kinross, including Kraftwerk, Travis, Stereophonics, alt-J, Ocean Colour Scene and Rihanna, who headlined the main stage on Saturday.

Festival director Geoff Ellis said: "We've had incredible performances from some of the biggest bands around the world as well as some future headline stars. I have to say one of my best bookings this year was the sun. You'll all be pleased to know I've rebooked it for 2014.

"I also want to thank the T in the Park crowd, who have once again proved they are the best in the world with praise coming from so many artists, including Rihanna, who said she'd never felt such incredible energy from an audience."

Hot, dry weather prevailed throughout the event, with temperatures reaching a high of 26°C (78.8°F).

These conditions contributed towards the use of more than 8000 sachets of sunscreen, as well as the consumption of 700,000 litres of water and 104,500 ice creams.

There was a rise in the number of medical visits from 810 in 2012 to 1160 this year, largely due to the weather.

Neil Gillies, from the onsite medical services, said: "Our team has attended to a lot of people this weekend but, in the main, this has been folk with minor problems like hay fever and asthma or those who hadn't heeded our advice to wear sunscreen or keep hydrated."

There were also 91 arrests made during the festival, which is an increase from last year's 30, but police have said this is due to a more proactive approach to the festival. The majority of crimes were for minor drug offences and petty crimes, police said.

Superintendent Rick Dunkerley said: "It's been another tremendous event from a policing perspective.

"While arrests are up on last year, this is due to the pro-active efforts of our officers who worked closely with stewards to ensure it was a safe and enjoyable event for the audience, as well as maintain the excellent, positive response of those attending at T in the Park."
