Mexican authorities have identified the use of the encrypted messaging application Threema as a key tool in communication between members of organized crime and colluding police, particularly in the state of Colima.
According to recent investigations, at least eight municipal police officers in Manzanillo were arrested for allegedly leaking gleaming information to the Jalisco New Generation Cartel (CJNG).
The agents would have shared data in real time about operations, arrests and security movements through this digital platform, according to the newspaper El Financiero.
The leaked information included strategic details of the state security system, which would have allowed the criminal group to anticipate actions by the authorities and facilitate their illicit operations.
Threema is a messaging application developed in Switzerland that is distinguished by its high level of privacy. Unlike other platforms, it does not require a phone number or email to create an account, allowing users to remain anonymous.
