Brazilian authorities have arrested the chief financial officer of the Venezuelan criminal organization, Tren de Aragua, at Rio de Janeiro’s airport. The suspect is accused of laundering approximately 300 million Brazilian Reais (roughly $60 million USD) through cryptocurrencies. He is also alleged to have coordinated the procurement and distribution of military-grade weaponry for the gang. Authorities are currently seeking an additional 25 members of the organization. The arrest represents a significant blow to the financial operations of Tren de Aragua, a group known for criminal activities across South America. Investigations are ongoing to dismantle the network and recover the laundered funds. This operation highlights the increasing use of cryptocurrency in transnational criminal enterprises.
