Police detained around 12 people this weekend after violence broke out at the end of the Download festival.
Leicestershire police were called to the festival site when fires and bursts of violence were reported. When they arrived on the scene, missiles were thrown and abuse was aimed at police officers, though no-one was seriously hurt.
The violence closely followed high praise from the police force for festival organisers and attendees as the number of arrests had been kept to only four the whole weekend.
Superintendent Les Milner has now called for any witnesses who may have recorded incidents on camera phones or other apparatus to get in touch.
"The disorder involved a number of people and it is not clear at this early stage what sparked the trouble," he said.
Around 12 of the worst trouble makers have been arrested and could face charges of assault and criminal damage.
