The Diekirch prosecutor's office is still conducting an investigation into the illegal rave held in a protected area near Heinerscheid at the end of July, which required a heavy police presence to disperse the partygoers.

In response to a parliamentary question submitted by DP MP André Bauler, ministers Léon Gloden and Serge Wilmes said the topic of unauthorised gatherings of this nature would be discussed over the coming weeks in meetings between the police and Clervaux council, to establish a protocol for dealing with other such raves in future.

According to the ministers' joint response, the police were unable to take action any earlier to break up the illegal rave at the end of July, as they would have otherwise had to take more aggressive action, which was unwanted by authorities.

Around 500 partygoers parked illegally in nearby villages, before walking to the rave in the Our valley, a Natura 2000 nature conservation area. 
 
Gloden and Wilmes said they did not think it made sense to map potentially sensitive areas and habitats in the run-up to any parties, as typically the organisers are very flexible and mobile.

At the rave in July, officers seized four trucks,  a dozen vans and 70 pallets containing sound equipment and tents, which are currently being stored in a police depot. Nineteen people were detained by police and officers also reported a number of drug violations. Two arrests were made in connection with the import of illegal substances intended for sale or consumption.
