Five drugs offences, one public order offence, one robbery of personal property and 13 thefts have been recorded since Wednesday, as well as one report of rape.

Arrests have been made on suspicion of robbery, fraud, drugs possession and supply offences and public order offences.

Two people have been arrested in connection with the rape offence.

Chief Inspector Dave Parker said: “We urge members of the public not to bring valuables to the site unless they need to do so.

"If you do need to bring valuables with you, we are offering free clear plastic wallets to festival goers which can be used to safely keep valuables such as car keys, mobile phones and cash, with you at all times. These are available on entry to the site. Festival organisers are also providing lockers on site to store larger personal items.

“Do not leave valuables on show, either in your tents, in open bags or in your back pocket, as we have had some pick-pocketing incidents. We are keen for everyone to have an enjoyable experience at the festival.

“I know many people will be celebrating their A-level and GCSE results and officers are working to make sure this is a safe environment in which to have fun.”
