Dutch and German Authorities Arrest Five in Suspected Gold-Laundering Network Involving Up to €210 Million

Dutch and German law enforcement authorities have arrested five individuals as part of a multinational investigation into a suspected money-laundering network that allegedly converted criminal proceeds into gold and transported the precious metal from Germany to Turkey. The operation, conducted on 7 October 2026 with support from Europol, involved approximately 500 police and customs personnel and resulted in searches across the Netherlands and Germany.

The latest details were released by Dutch police on 4 November. Four men, aged between 43 and 59, were arrested in Germany, while a 55-year-old man from Rotterdam was detained in Eindhoven. The Dutch suspect is believed to have acted as an illegal financial intermediary, commonly described as an underground banker, and is suspected of handling cash transactions totalling approximately €60 million. His precise involvement remains under investigation, and the figure represents suspected cash flows rather than funds seized by authorities.

The investigation concerns a predominantly Turkish-German criminal organisation suspected of providing money-laundering services to other criminal groups. According to investigators, the network may have processed proceeds from criminal activities, probably including drug trafficking, by converting cash into gold and moving the resulting assets across borders. Police estimate that between one and four tonnes of gold, with an estimated value of €55 million to €210 million, may have been transported to Turkey over a six-year period.

The suspected operation involved several stages designed to obscure the origin and movement of criminal funds. Investigators believe that cash supplied by criminal clients was used to purchase old jewellery and scrap gold through cooperating jewellers, particularly in Germany. The gold was then melted down and converted into bars before being transported to Turkey using specially modified vehicles or air routes.

Once in Turkey, the gold was allegedly processed into high-quality jewellery. The resulting products were reportedly used to settle payments with the network’s criminal clients. In other instances, jewellery or processed gold was allegedly transported back to Germany outside the proper customs procedures to compensate the jewellers involved in the original purchases. This arrangement potentially enabled the network to transfer value internationally while separating the original cash proceeds from the final assets received by its customers.

The Dutch suspect is believed to have played a role in receiving and forwarding substantial cash payments. Police suspect that he was connected to the wider organisation and acted as an intermediary outside the regulated financial system. Such underground banking arrangements can facilitate the movement of funds without conventional bank transfers, making it more difficult for authorities to trace the original source of money and identify the ultimate beneficiaries.

The investigation began in October 2023, when German traffic police stopped a specially modified vehicle during a routine motorway control. Officers discovered several kilograms of gold and almost €500,000 in cash concealed inside the vehicle. The discovery prompted further enquiries into the origin of the assets and the individuals involved in their transportation. In a separate proceeding, money and gold with a combined value exceeding €4 million were confiscated.

Subsequent investigative work uncovered suspected links to a wider international network and a possible system for laundering money through the gold trade. Authorities believe that the organisation offered these services to third parties, effectively operating a Crime-as-a-Service model in which criminal groups could use an intermediary network to convert and transfer illicit proceeds. The precise number of clients and the full extent of the suspected activity have not been publicly established.

The coordinated operation on 7 October involved searches at two locations in Rotterdam and Eindhoven, as well as searches in the Dutch towns of Sliedrecht and Zwijndrecht by German police. Approximately 40 additional locations were searched across several German states. The scale of the operation reflected the cross-border nature of the suspected activities and the need to coordinate investigative measures across multiple jurisdictions.

In the Netherlands, the searches resulted in the seizure of digital data carriers, approximately €10,000 in cash, a vehicle and real estate. German authorities seized property valued at no less than €2 million, 19 vehicles, approximately €100,000 in cash and a substantial quantity of melted gold and silver bars. The four suspects arrested in Germany were brought before an investigating judge. The authorities have not provided a consolidated valuation of all seized assets, and the seizures should not be confused with a final confiscation of criminal proceeds.

Europol supported coordination between the Dutch and German investigative teams in preparation for the operation. The investigation was conducted by Dutch and German police, with German customs also participating in the coordinated action. Authorities continue to examine the suspected transport routes and the possible involvement of additional individuals.

The case illustrates how precious metals can be used as an alternative mechanism for moving and disguising criminal wealth. Gold is particularly attractive to money launderers because it is highly valuable relative to its size, can be melted and transformed into different forms, and can be traded across international markets. Converting cash into scrap gold, bullion and subsequently jewellery may complicate the reconstruction of the original ownership and source of funds, particularly where transactions involve multiple businesses and intermediaries.

For financial institutions, precious-metal dealers and other regulated businesses, the investigation highlights the importance of examining the commercial rationale and economic substance of transactions involving gold. Relevant risk indicators may include unusually large cash-funded purchases, unexplained third-party payments, inconsistent trading volumes, unclear ownership of goods and repeated cross-border movements that lack adequate commercial documentation. Where appropriate, customer due diligence should extend to identifying beneficial owners, understanding the source of funds and assessing the purpose of transactions and the relationships between counterparties.

The suspected use of underground banking also reinforces the importance of considering financial activity beyond the conventional banking system. Criminal proceeds may be transferred through networks of cash intermediaries, commodity traders and businesses operating across different jurisdictions. Consequently, individual transactions that appear commercially plausible in isolation may require further scrutiny when considered alongside related payments, movements of goods and the wider customer relationship.

The investigation remains ongoing, and the five arrests do not amount to findings of guilt. The estimated gold volumes and values, as well as the approximately €60 million in cash attributed to the Dutch suspect, remain investigative estimates or allegations. Further enquiries will determine the precise roles of the suspects, the extent of the network's activities and whether additional individuals or businesses were involved.
