Polish prosecutors arrested nine suspects over an alleged PLN 337 million money-laundering scheme tied to proceeds from internet fraud. The investigation led to coordinated operations across Łódź, Warsaw and the Małopolska region, with seven people placed in pre-trial detention after arrests on suspicion of laundering funds and taking part in an organised criminal group. Prosecutors say the group allegedly moved victim money into bank accounts, across borders and ultimately into cryptocurrency. The Regional Prosecutor’s Office in Łódź estimated that between February 2025 and July 2026 the suspects handled around PLN 337 million in funds whose illicit origins they allegedly tried to conceal. Authorities stressed the figure is an estimate of the suspected laundering scale, not a confirmed amount recovered. Investigators describe a chain starting with online deception. Suspected methods included misuse of Poland’s BLIK payment service and impersonation schemes involving supposed bank employees or representatives of investment platforms. Prosecutors allege cash was collected via cash couriers and exchange office staff. High-value vehicles reportedly took drivers to meeting points, with a torn banknote photo showing its serial number used as a recognition signal. Investigators also allege that codes sent to a cashier and a courier helped them bypass normal AML procedures during certain transactions. After cash was collected, prosecutors say some money was deposited using cash-deposit facilities operated by a cooperating company, then transferred through bank accounts linked to connected entities. Other funds were allegedly carried across national borders in specially prepared vehicle compartments. Prosecutors suspect fictitious gold trades were used to provide cover for transfers, described as probable rather than fully established. They also say most of the money ultimately reached cryptocurrency, without identifying specific assets, blockchain networks, custodians, wallet addresses or conversion mechanics. During enforcement actions, police carried out searches that produced more than PLN 1 million worth of currency and gold, along with computers, mobile phones and other data carriers. The operation involved the Central Bureau for Combating Cybercrime, the Warmian-Masurian Border Guard unit and the Internal Security Agency, under prosecutorial direction and supervision from the National Prosecutor’s Office cybercrime department. All nine suspects, aged 26 to 53, face allegations of participation in an organised criminal group and money laundering. Some also face allegations relating to failure to report suspicious transactions to Poland’s financial intelligence authority, the General Inspector of Financial Information. Seven remain in pre-trial detention, while two cashiers are on financial guarantees, police supervision and restrictions on leaving Poland, as the investigation continues without any announced convictions.
