Patrolling officers passed a van shortly after 8:30 PM on Sunday evening on Roemer Visscherstraat emitting a strong hemp odor. The officers checked the three occupants and the van. Inside the van, they found a firearm. The three occupants, all Dordrecht residents aged 36, 38, and 39, were subsequently arrested.

Searches were conducted at the home addresses of the arrested suspects, including on Bosboom-Toussaintstraat. The van was seized for further investigation.
