From the Taskforce Underground Banking (TF-UB), the National Investigation and Interventions Unit, led by the National Prosecutors Office, initiated the investigation. They tracked the criminal organization based on information from data from the messaging service SKYECC. Earlier, two suspects had already been arrested in this case. They were convicted to prison sentences.

The suspicion is that the suspect was involved in laundering an amount of at least 44.5 million euros and 5.8 million dollars from April 2019 to November 2020. Additionally, he is suspected of dealing in hashish and cocaine. The man will be transferred to the Netherlands shortly, where he will be brought before the examining magistrate.
