T In The Park clean-up starts after festival's end The two-week clean-up operation following the 20th anniversary of Scotland's biggest music festival has begun. Workers begin cleaning up T In The Park after festival's end on Sunday David Guetta and The Killers were among the headliners for the festival's last day Rise in number of medical visits due to hot weather, and 91 arrests made Festival favourites The Killers played the final headlining set on the main stage of T in the Park to a crowd of thousands while David Guetta lit up the sky with blazing lights from the Radio 1 stage last night. Over three days more than 200 acts performed at Balado, Kinross, including Kraftwerk, Travis, Stereophonics, alt-J, Ocean Colour Scene and Rihanna headlining 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, but I have to say that one of my best bookings this year was the sun - and you'll all be pleased to know that 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 26C (78.8F). These conditions contributed towards the use of more than 8,000 sachets of sunscreen, the consumption of 700,000 litres of water and 104,500 ice creams eaten. There was a rise in the number of medical visits from 810 in 2012 to 1,160 this year, largely due to the weather. Neil Gillies, from the on-site 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 pro-active 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 police 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. Although there was no sign of fake ecstasy tablets, police have reissued a warning about them. Mr Dunkerley added: "The reaction and responsible attitude to our warnings regarding "green rolex" has been very positive but should not be confined to T in the Park. We urge people to generally be aware, to continue to take care, avoid these poisonous pills and keep safe at all times. Indeed, they come in various colours and designs. They are dangerous, unstable and unpredictable. T In The Park 2013 gig reviews
