Police have found 400 kilos of crystal meth with a street value of around €80m at a drugs lab in Wateringen in the province of Zuid-Holland.

Six men aged between 26 to 53 were arrested at the scene, after police raided the premises in the early hours of Tuesday morning.  Apart from the methamfetamine, police also found MDMA, the central component of ecstasy, and various vats of chemicals.

Regional broadcaster WOS.nl said the owner of the premises had moved his car company to The Hague and had rented out the warehouse at the Wateringen business park.

‘The lights were often on during the night’, a woman who worked in an adjacent building told the broadcaster.
