In Brazil, a significant operation termed 'Operação Regresso' commenced on the morning of Saturday, January 21, 2025, targeting suspects affiliated with a criminal faction responsible for numerous attacks in the state of Rondônia. This operation involves the collaboration of both state and federal security forces and aims to enforce 26 preventive arrest warrants across various municipalities including Porto Velho, Candeias do Jamari, Guajará-Mirim, and Ouro Preto do Oeste, and extends to other locations such as Rio Branco in Acre and Catanduvas in Paraná.

The Public Ministry of Rondônia (MP-RO) announced that the operation's primary targets are individuals implicated in criminal activities that escalated following 'Operação Escudo' in 2025. This previous investigation uncovered a series of violent incidents, including assassination attempts against public officials, vandalism of public buildings, and arson targeted at both public and private vehicles. The extensive operation signals a determined effort by authorities to address the ongoing threat posed by organized crime in the region.

Many of the suspects involved had previously been released provisionally after being interrogated and placed under certain precautionary measures, indicating a complex legal backdrop to their continued criminal activities. The current operation not only aims to recapture these individuals but also highlights the broader struggles faced by law enforcement regarding organized crime and the challenges of ensuring public safety in regions affected by such violence.
