It proved impossible for them to track down the individual who had thrown the stone which hit the policeman, but their investigations led to the prosecution of six men who helped arrange the event.
Anyone who comes to rural Wales to do this kind of thing will be dealt with harshly 
“The police knew about internet sites which are used by the ravers,” said Detective Constable Maldwyn Roberts, one of a team of investigating officers.
“We used pictures they had posted on one of the sites after the event, video footage from the police helicopter, and evidence we had collected when we stopped people as they left the site to bring a prosecution,” Dc Roberts added. The police say the successful court case – using legislation which has been little used by North Wales Police in the past – gives out a clear message.
Although the guy that threw the stone wasnt caught it was due to the web photos that the organisers were punished, which i think is total bollocks. Why should the people who organise it have to be prosecuted due to the actions of one lone individual.
