Police have arrested 17 people after raiding what is thought to be the largest cocaine factory ever found in the Netherlands.
About 100kg of crack cocaine and tens of thousands of litres of chemicals were discovered when detectives raided a former horse riding school.
Inside the laboratory, which lies 75 miles (120km) northeast of Amsterdam, they found sleeping quarters and recreational areas.
Chief Inspector Andre van Rijn said the laboratory was able to produce cocaine with a street value of €4.5m to €6m (£4m to £5.4m) every day.
He added: “This is the largest cocaine laboratory ever found in the Netherlands.
“Given the number of people who worked there, the installation, the size, the furnishings and the equipment, we estimate the production capacity at 150kg to 200kg of cocaine per day.”
Police footage showed equipment and supplies including plastic barrels, vats of chemicals and a row of five red cement mixers, used to extract cocaine from products like clothing that are impregnated with the drug before being exported to the Netherlands.
Most of the suspects were arrested at the lab. Thirteen of those in custody are Colombians, three are Dutch, and one is Turkish.
They are due to appear before an investigating magistrate on Wednesday and Thursday.
Detectives are continuing their investigation.
