Ecstasy, ketamine and more than 200 canisters of laughing gas have been discovered buried in the grounds of the Creamfields festival site.Up to 80,000 ravers are set to descend on Daresbury in Cheshire this week for the four-day music festival.Ahead of the festival's opening on Thursday, police searched the grounds as part of 'disruption work', trying to stop 'brazen' revellers from burying drugs ahead of the event.In a week of searches, specialist officers uncovered 204 canisters of nitrous oxide as well as large bags containing ecstasy, MDMA and ketamine tablets.Cheshire Police said it would continue the searches in the run-up to the event.More than 250 artists will perform across the week, including Calvin Harris, Tiësto, Martin Garrix and Swedish House Mafia.Superintendent Andy Blizard said: 'Every year we remind those attending Creamfields that there is a zero-tolerance policy regarding drugs and, every year, we counter a number of brazen individuals who think they can outsmart us by concealing drugs from view or burying them at the site months in advance.'Our specialist search teams have spent a considerable amount of time combing the grounds of the Creamfields site ahead of the festival's opening later this week.'We fully expect to find further quantities as our searches continue, leaving many of those who chose to bury these items very much disappointed to find them no longer where they left them when they arrive at the festival to dig them back up.'Anyone who has buried a rucksack or holdall bag at the site and would like it back is asked to get in contact with us – officers have already begun conducting enquiries to identify their owners and look forward to speaking to them soon.' More than 200 canisters of nitrous oxide have been discovered by officers from Cheshire Constabulary hidden around the site in Daresbury, near Warrington Tablets marked 'It's Coming Home', which was among a large quantity of Class A, B and C drugs found by police Green tablets with the word 'Cornetto' were also found buried underground at the festival siteIn the past, revellers have been caught using extravagant methods to try and smuggle drugs into the festival. In 2024, two men were jailed for attempting to smuggle ketamine into the site using Kinder Eggs stuffed up their bottoms.Marshall Maddock – who was already under investigation for separate drug offences – and Harry Hewitson were caught by sniffer dogs on their way into the Cheshire festival.The duo were jailed for 18 months each after Maddock, 21, admitted to possession of Class A drugs (cocaine) and possession of Class B drugs (ketamine) with intent to supply and Hewitson, 22, pleaded guilty to possession of Class B drugs (ketamine) with intent to supply.On their uncomfortable trip to Creamfields' North Gate on August 25, 2023, the pair passed amnesty bins giving them the opportunity to ditch the illegal items.But Chester Crown Court heard that a drugs dog picked them out on their way in, leading to officers conducting a search.Last year Sian Bullock, 35, attempted the same Kinder Egg stunt to try and smuggle more than 60 MDMA pills into the festival.The care support worker, from Thornton Cleveleys, Lancashire, admitted to police she had tried to smuggle 64 tablets in by hiding them inside her body in the toys but was rumbled after sniffer dogs alerted security staff. Police estimated the drugs had a potential value of up to £630 but Bullock claimed she was unaware.She told officers she didn't know what the drugs were but admitted she had bought them for personal use.Despite claiming she did not know what the MDMA pills were, she was charged with possession with intent to supply class A drugs and appeared at Chester Crown Court on Friday, May 16.

The officer attempted to allow Mr Green more space from other cars before they noticed his vehicle was edging closer to them. They repeatedly signalled for Mr Green to stop but he continued and drove the car into their leg. The police officer was unharmed but they admitted it could have been different had they not been wearing protective motorcycle boots.Bags of cocaine and ketamine were found in Mr Green's camping gear, which he claimed he had only picked up to put in the bin.Mr Green admitted to taking cannabis and cocaine at the festival, but said he had done so around 24 to 36 hours before driving. He denied taking ketamine.
