Czech police have moved to detain darknet marketplace founder Tomas Jirikovsky over a $45 million Bitcoin scandal. The high-profile arrest links directly to the political downfall of former Justice Minister Pavel Blazek earlier this year.
Authorities confirmed the operation on Thursday, with Chief State Prosecutor Radim Dragoun stating they were “securing people and things” in a criminal case recently separated for independent proceedings.
Local media revealed that officers apprehended Jirikovsky during a late-night raid at his home. He allegedly tried to escape by climbing onto his roof, but police captured him soon after. His ex-wife confirmed the intervention, citing a neighbor’s call about the rooftop standoff.
Jirikovsky is a Czech programmer infamous for creating Sheep Marketplace in 2013. The illegal darknet platform traded drugs, weapons, and counterfeit goods. According to Seznam Zprávy, he generated around 680 BTC from operations before shutting it down in December 2013. He then stole an additional 841 BTC from platform users, boosting his fortune to at least 1,500 BTC.
In 2017, the Brno Regional Court sentenced him to nine years for embezzlement, drug trafficking, and arms possession. However, he secured early release in 2021 after serving half his sentence.
In addition to his criminal history, Jirikovsky allegedly paid Blazek 468 BTC to avoid being sentenced to another prison term. According to reports, the money is connected to Nucleus, a different darknet marketplace that has 5,000 Bitcoin in its wallet.
Following public indignation about his ties to a convicted dealer, Blazek resigned in May as a result of the Bitcoin donation.
Things became more heated when blockchain analytics company Arkham Intelligence discovered a $77.5 million Bitcoin transfer from a Nucleus wallet in March 2025. This was the first time the money had moved in nine years.
Lucien Bourdon, a Bitcoin analyst at Trezor, stressed that criminal activity on Bitcoin leaves permanent traces. “Large transfers can be traced forever. Imagine if every fiat transaction involving governments was just as visible,” he said.
Consequently, this arrest fosters a tighter net around illicit crypto dealings in Central Europe. Moreover, it shows how transparent blockchain technology becomes an instrument at exposing and putting an end to top-level financial misconduct.
