Brussels police discovered more than 2,500 cannabis plants at seven illegal plantations in Brussels and Flanders.

Police made 15 arrests and confiscated more than 2,500 cannabis plants as well as several cars, a large, undisclosed sum of money and 14 kilograms of ready-to-be-used cannabis.

The individuals who were arrested will be interrogated later this afternoon. An investigating judge will decide whether the suspects will continue to be held in police custody after the interrogations.

The house searches were part of a large-scale drug operation by local police that began four months ago, and that saw 180 officers raiding 14 homes early this morning in Auderghem, Forest, La Hulpe, Wezembeek-Oppem as well as at other locations.

The individuals who were arrested are suspected of having operated a drug ring that had been active in the Brussels region for months. Several of the homes the police raided had tick metal doors that had been outfitted with additional locks for extra security.

A spokesperson for the Brussels prosecutor’s office told Het Nieuwsblad that the entire drug ring had been dismantled as a result of the police operation.
