A lab for the production of the illicit drug pervetin, uncovered by the police on Wednesday in the region of Karlovy Vary, was capable of producing dozens of kilos of the methamphetamine worth tens of millions of crowns. The police commented it was not often they saw a facility of comparable size. Three people, reportedly of Vietnamese descent, were arrested and several kilos of the drug were seized. The Czech News Agency reported it took officers equipped with gasmasks two trips with a transport vehicle to remove chemicals from the facility. Early estimates suggest that more than 50 kilos of pervetin were produced at the site.
