International operation in Sereď: Cryptocurrency fraud totalling more than €8.4 million
Financial police officers from the national centre for combating organised crime conducted an extensive raid in recent days. The operation, codenamed MIDAS, targeted fraudsters who offered clients profits from digital assets that never existed via websites and telephone centres.
The total damage reached more than €8.4 million. A total of 1,125 victims have been identified so far, according to Sereď Online.
The raid took place within a joint investigation team established by the prosecutors' offices of the Slovak Republic and the Czech Republic. Europol and Eurojust provided operational support. Home searches and searches of other premises were carried out in Bratislava and Sereď.
Police officers detained 11 people. Luxury assets were seized including motor vehicles, watches, jewellery, gold coins and bars. Computers, mobile phones, cash and crypto-assets were also confiscated.
On Slovak territory, four individuals were charged. In the Czech Republic, four more individuals and two companies face charges. On 2 July 2026, the Specialised Criminal Court in Banská Bystrica remanded all four Slovak suspects in custody.
The group operated under the brands SEIF FINANCE, SEIF GROUP, SEIF DAO and CRYPTO CARTEL. It offered advantageous investments in cryptocurrencies and NFTs. However, the financial resources from clients were not invested anywhere.
The Regional Prosecutor's Office in Bratislava is overseeing the entire case. The police force again warned citizens to exercise increased caution when investing.
