Three men are to appear before court charged in connection with organising an unlicensed music event in Swanley, Kent which caused £30,000 of damage.
At around midnight on August 6, 2017 up to 500 people were reported to have entered an industrial unit without the owner’s consent.
An illegal music event was alleged to have been held at the premise and when Kent Police attended the scene 12 people were initially arrested.
Equipment relating to the event was also seized.
Following an investigation, three individuals - Germantas Citavicius, 19, Tomas Rudzevicius, 20 and Lee Johnston, 29 - were all charged with conspiracy to cause a public nuisance.
All three have been bailed to appear before Maidstone Magistrates’ Court on 17 November.
Superintendent Amanda Tillotson said: "It is estimated that as a result of the large crowds attending this unlicensed music event more than £30,000 worth of damage was caused to a brand new warehouse, which is simply unacceptable.
"Events such as these remain rare anywhere in Kent, but when they do take place they can attract considerable numbers of people often to industrial units.
"Many who travel into the area, do so from outside the county by using trains. These gatherings can cause a number of issues, including damage to property, noise to local residents and antisocial behaviour. The nature of the venues can also pose real safety issues for those attending.
"I’d like to reassure residents and businesses that we continuing to work closely with our partners, including the Metropolitan Police and British Transport Police, to detect and disrupt any plans people may have to stage or attend unlicensed music events in Kent. We will not tolerate the disorder they can cause and will take robust action against anyone we suspect is breaking the law."
