Polish prosecutors stated that the Katowice court has approved pretrial detention for Roman Ż. He is accused of participating in organized crime and embezzling client funds through computer fraud.
The prosecution stated that the involved group is suspected of transferring at least 7.8 million zlotys, approximately $2 million, from exchange users. The charges also include altering exchange data and interfering with data processing and transmission procedures.
The case continues to expand.
The investigation has expanded to include multiple suspects. Last week, three additional individuals were detained for three months. Prosecutors stated that the case is related to a plan to seize the assets of Zondacrypto’s founder, Sylwester Suszek.
The exchange previously froze withdrawals.
Zondacrypto was originally founded in Katowice under the name BitBay, later relocating to Estonia and rebranding in 2020. The company claimed to have 1.3 million customers, mostly from Poland.
The prosecution also stated that nearly €8 million was transferred from the operator’s account in October 2025 to purchase property in France. Additionally, a €2.9 million loan was recorded as repaid, although it was never actually settled.
