Police discovered 19 marijuana plantations, a quantity of hard drugs, an illegal cafe and equipment to make amphetamines after sealing off an area of 140 houses in the Limburg town of Hoensbroek on Tuesday.

In total, 18 people were arrested but more arrests are likely to follow.
Some 250 police officers were involved in the search, which took place between 7.30 and 15.30. No-one was allowed to enter the area and locals could only leave to go to school or work while the search was carried out.
The decision to carry out the massive check followed reports from energy firm Essent about a sudden surge in energy use – usually associated with indoor marijuana growing.
It is unclear how many marijuana plants were seized, but according to Nos tv, electricity was being illegally tapped in seven of the 19 plantations.
