The police arrested six people on Thursday night when they rolled up a drug lab in Vorstenbosch in Brabant. The laboratory was found in a riding school.

The police found the drug lab in a hidden area at the riding school. The space was shielded with straw packs, the police reported on Friday.

When they raided, the police arrested two men (aged 32 and 37) who were in the drug lab and four who slept in the property.

In the drug lab, the police found advanced equipment capable of producing a "substantial amount of synthetic drugs". Several hundred liters of raw materials were also stored for the production of drugs, including BMK, phosphoric acid and caustic soda.

The drug laboratory has been dismantled by experts from the National Dismantling Facility (LFO).
