The Civil Police of Mato Grosso do Sul conducted a significant operation, named 'Matrioska', leading to the arrest of 28 individuals believed to be part of an organized crime group involved in drug trafficking and money laundering. This operation was executed in Campo Grande on the 25th and involved search and seizure warrants as the authorities aimed to dismantle the criminal organization. Key to this investigation is an inmate who, despite being incarcerated in a maximum-security facility, is alleged to have orchestrated the operations of the organization from behind bars.

The investigations revealed that the leader of the group had maintained control over drug distribution and finances while serving his sentence. Authorities reported that he decided on drug transportation routes and coordinated logistics from within the prison. The organization was primarily transporting drugs from Mato Grosso do Sul to the southern region, specifically to Pato Branco in the state of Paraná, using women to carry out the transport via commercial buses.

This arrest and the operations undertaken suggest a significant challenge to law enforcement in combating organized crime in Brazil, highlighting the complexities of managing crime that operates from within the prison system. The collaboration between different police departments, including the Civil Police of Paraná and the Department of Corruption and Organized Crime Prevention (DRACCO), signifies a united front against such criminal activities, aiming to disrupt and dismantle these networks effectively.
