Bags and bags of crystal meth were guarded by a dozen police officers, rifles in hand. The National Police force was heavily deployed, and around twenty officers from the Verneda police station in Barcelona watched curiously from a distance. 582 kilograms and 722 liters of MDMA oil were seized, the largest operation against a synthesis laboratory for this drug in Spain and one of the largest in Europe. In this case, the material—which would have had a final value of 31 million euros—was seized in a warehouse in an industrial estate in Amposta (Montsià), and five arrests were made. Four of those arrested, all Dutch nationals, were sent to prison.
