Some festival-goers at this year's Virgin V Festival found themselves leaving the event in a police car, as 41 people were arrested for offences including drug dealing and theft.
The festival, which was held at Weston Park, saw stars including Jay-Z, Jess Glynne and Madness head to Staffordshire for a weekend of live music.
Officers from Staffordshire Police joined security staff at the event to keep visitors safe, and crack down on crime. Routine bag searches at the entrances found dozens of people attempting to smuggle drugs into the festival, which took place on Saturday, August 19 and Sunday, August 20.
Among the substances smuggled into the event were MDMA, ecstasy, cannabis, cocaine, ketamine and more than 300 cannisters of nitrous oxide, also known as laughing gas.
Officers had to issue a health warning after some of the drugs seized by officers, mainly Pentylone and N-Ethlpentylone, were identified as being potentially dangerous if consumed.
Other music festivals across the country have seen people who have taken the drugs needing urgent medical attention, suffering with nausea, vomiting, hypothermia, insomnia and agitation.
Plain clothes officers identified six men who were distributing drugs between them with intent to deal them to festival-goers. After a search of the men's tents, officers found large quantities of what is believed to be ecstasy and cocaine, and all six were arrested on suspicion of possession with intent to supply.
Staffordshire Police said that 14 men had been arrested in connection with drug dealing, two for assault, one for the possession of an offensive weapon and another for fraud.
On Friday, a 17-year-old boy was arrested after he tried to sneak 200 tablets into the festival and a 16-year-old was also ejected from the event after officers found 28 MDMA tablets on him.
Superintendent Martin Brereton, commander for the V Festival operation, said: “Thank you to everyone who attended V Festival, barring an irresponsible few the event passed peacefully with thousands of people having the time of their lives. Our officers engaged with lots of members of the public, lots of selfies were taken and initial feedback has demonstrated that the public welcomed and were comforted by the visible presence of armed officers alongside unarmed officers.
“Our security operation was a fantastic success as we worked closely with the event organisers and partners to plan ahead and be prepared for every eventuality. Our unpredictable and extensive police deployment saw officers all over the site at different times, creating a safe and secure environment.”
