The Judiciary Police (PJ) cooperated with the FBI in the arrest of an American man in Lisbon, suspected of laundering millions of euros through the cryptocurrency website Samourai Wallet, which he co-authored with another suspect, also already arrested in the USA. According to the American authorities, who released the indictment, the man arrested in Lisbon is called William Lonergan Hill, is 65 years old, and is not only the founder of Samourai Wallet but also the company's Chief Technology Officer. The suspect, who was arrested on the morning of last Wednesday, April 24, allegedly used the website to launder fortunes of criminal origin, moving more than a billion dollars in bitcoins and more than 680 million dollars in BTC. The suspect arrested in the USA is called Keonne Rodriguez and is 35 years old. The company's co-founder and CEO was 'caught' in Pennsylvania also on Wednesday morning. Both have already been brought before a judge, for the first judicial interrogation, and are in preventive detention. William is now awaiting his extradition to the USA. In turn, the Samurai Wallet was closed and the servers as well as the domain seized. According to the American authorities, a "seizure warrant for the Samurai application" was also delivered to the Google Play Store, so that it is no longer available for download. In a publication shared in the Department of Justice of the state of New York, the US attorney, Damian Williams, explains that what is at stake is money laundering "on a large scale". For 10 years providing criminals with a "virtual refuge" James Smith, head of the FBI, reveals that the suspects had been carrying out this criminal activity "for 10 years" and that this "provided other criminals with a virtual refuge for the clandestine exchange of illicit funds". "The FBI is committed to catching all these secret financial schemes and ensuring that no one can hide behind a screen to perpetuate financial irregularities", adds the official. According to the American authorities, the suspects attracted "other criminals" through the social network X, formerly Twitter. For example, in July 2022, when the war in Ukraine had already begun, they welcomed "new users of the Samourai Wallet Russian oligarchs", in clear disregard for the sanctions applied by Europe and the USA. Both risk a maximum sentence of 20 years in prison. Read Also: Founder of cryptocurrency platform arrested in Lisbon for laundering fortunes (Portuguese version)
