An employee of Banco Nación was arrested in the Buenos Aires neighborhood of Caballito, accused of being part of a criminal network that stole money from bank accounts through identity theft. The case was uncovered following a report of an irregular withdrawal of 28 thousand dollars.
The scheme, according to judicial sources, involved accessing sensitive data from the bank's internal system. The worker used it to authorize fake transactions and thus facilitate the actions of a criminal structure dedicated to cloning identities and committing financial fraud.
A repeated pattern in different branches
It all began when a Banco Nación client reported a withdrawal he never authorized. Someone had impersonated his identity and withdrawn 28 thousand dollars from a branch.
The investigation detected similar operations in bank branches located in Ciudad de Buenos Aires, Morón, and Pilar. The modus operandi was repeated: use of confidential information, fake documents, and authorizations issued from within the bank's system.
After months of intelligence work, investigators confirmed that an employee of Banco Nación was the one accessing the accounts and authorizing the transactions. The evidence pointed to the same worker also being actively involved in the fraud schemes.
With a court order, his home in Caballito was raided. There, two cell phones that were allegedly used in the illicit operations were seized. The 30-year-old man was removed from his position and charged with fraud, document forgery, and embezzlement.
The million-dollar fraud against UBA and the connection with an organized gang
Weeks earlier, another blow shook Banco Nación: a fraud of 1.591 billion pesos against the University of Buenos Aires. The leader of the gang, nicknamed "La China," was arrested on May 5.
According to police sources, the woman led an organization that channeled funds through third-party accounts. The objective: to reintegrate the money into the financial circuit and make it difficult to trace.
The authorities of the UBA's Law and Dentistry faculties reported irregular movements in October of last year. The criminal group allegedly posed as Treasury staff of the university to order 13 transfers totaling almost 1.6 billion pesos.
They also attempted to make three more transfers for an additional 341 million. The orders were sent by email from a fake address (tesoreria@ubatic.net.ar) and then delivered on paper, with forged signatures, through a supposed courier.
The Anti-Fraud Division, along with Federal Criminal and Correctional Prosecutor's Office No. 8, led by Eduardo Taiano, deployed a surveillance, tracking, and authorized wiretapping operation.
Investigators identified 19 people who lent their accounts to channel part of the stolen money. In February 2025, several raids were carried out, and five key members of the organization were arrested, responsible for creating shell companies, forging documents, and operating internal links within the banking entity.
With these cases, a complex network was exposed that combined knowledge of the banking system, internal access, and a well-oiled forgery mechanism to carry out million-dollar frauds. The investigation remains open, and further arrests are not ruled out.
