Recent developments highlight international law enforcement actions against criminal networks involving Dutch interests. In October 2026, two Brazilian men were extradited from Portugal to the Netherlands to face charges for a series of violent robberies committed in Amsterdam and Haarlem in August 2024. These incidents included a violent home robbery and attacks on taxi drivers.

Simultaneously, Colombian authorities arrested two Dutch nationals, Ronny Haleber and Ulrich Van Dinter, in Medellín and Cali. Both men were subject to Interpol red notices. Investigators allege they acted as links between European criminal organizations and Colombian traffickers, facilitating the shipment of cocaine to the Netherlands and Belgium via ports and airports. 

Haleber is specifically accused of moving cocaine from Cali to the port of Buenaventura for shipment to Belgium and the Netherlands via Curacao. Van Dinter is alleged to have facilitated trafficking by contaminating legal goods at Colombian airports and ports. The Dirección de Asuntos Internacionales de la Fiscalía is managing the formal extradition requests.
