A multi-month investigation by the Public Ministry has resulted in the dismantling of the most significant money laundering network linked to the Tren de Aragua criminal organization operating in Chile to date. The operation, which led to the arrest of 18 individuals, marks a critical shift in how authorities are addressing the financial infrastructure of transnational crime.
Among those detained is José Carlos Pérez Asencio, a 33-year-old Venezuelan national and executive at Banco Santander. Investigators allege that Pérez served as a central figure in the organization, acting as a “presta cuentas” (account holder) who facilitated the movement of illicit funds through the formal banking system. His arrest represents the first instance of a bank employee being taken into custody for direct involvement with this criminal structure.
The Mechanics of the Operation
According to the investigation, Pérez utilized his professional background—which includes experience at Banco Santander since 2019 and a prior role as a credit specialist at the Banco de Venezuela starting in 2012—to obscure the origins of criminal proceeds. Between 2022 and 2025, he allegedly funneled money derived from activities such as the extortion of local business owners, often referred to as “vacunas,” through accounts at institutions including Scotiabank and Falabella.
The investigation into this financial network originated following a quíntuple homicide at a clandestine event in Lampa in July 2024. Evidence gathered from that scene revealed a previously unknown cell of the Tren de Aragua, eventually leading authorities to the sophisticated financial apparatus managed by Pérez.
Did You Know? The investigation into this network necessitated coordination between the Police of Investigations (PDI) and Gendarmería, as several members of the criminal structure were already incarcerated for unrelated offenses at the time of the operation.
Implications for Financial Security
Expert Insight: The infiltration of the formal banking sector by organized crime represents a significant escalation in the complexity of illicit operations in the country. By leveraging an “insider” with deep knowledge of credit and financial protocols, the criminal organization was able to provide a veneer of legitimacy to illegal gains for at least three years, posing a unique challenge to institutional monitoring systems.

The operation, led by the Fiscalía Regional Metropolitana Sur, resulted in significant asset seizures. In addition to the discovery of 15 million pesos in cash at the home of one of the suspects, authorities successfully froze more than $300,000 USD held on the Binance financial platform.
As the legal process continues, it is likely that authorities will focus on identifying further vulnerabilities in the banking sector that may have been exploited. Analysts expect that this case could lead to heightened scrutiny of internal compliance procedures and a potential increase in the monitoring of transactions involving high-risk profiles linked to the criminal structure.
