Thousands of revellers gearing up for Y Not Festival this weekend are being warned that drugs are not welcome through the gates.
Derbyshire police are working with the organisers of the three-day festival to ensure the event is safe and enjoyable for everyone.
Around 10,000 people are expected to attend the event in Pikehill which takes place this weekend.
As part of their work to keep the festival safe, officers will be teamed with security staff to search people arriving at the festival for drugs.
Police will be using a specially trained dog to sniff out drugs on festival goers as they enter the site. Anyone found with illegal drugs will not be allowed into the festival.
There will also be drugs amnesty bins that people can put drugs in anonymously.
