Bogotá police arrested Luis Saúl Pérez Nieto, alias Nairobi or Páez, a top Tren de Aragua (TdA) leader in Peru, tightening a multinational manhunt across borders. Authorities said the capture came after a seven-month joint investigation and information sharing between the Peruvian National Police, the Colombian National Police and the DEA, using special investigative techniques. Pérez Nieto was arrested August 27 in Fontibón, Bogotá. Colombian police identified him as a trusted associate of the deceased TdA leader Héctor Guerrero Flores, alias Niño Guerrero. He was linked to a range of alleged crimes, including extortion, international arms trafficking, targeted killings and drug trafficking along routes spanning South and Central America. The United States also wanted him on charges related to terrorism, money laundering, drug trafficking and criminal conspiracy. The case reflects how law enforcement connects intelligence and judicial action across countries. Police described two channels of cooperation: quick informal communications to share names and movements during active searches, and formal mutual legal assistance to support judicial orders, extraditions and other state-to-state steps. International policing links were also referenced, including INTERPOL and AMERIPOL. AMERIPOL said sustained action against TdA is a priority for 2026. The investigation also showed how arrests trigger further transfers. One day after Pérez Nieto’s capture, Colombia transferred Alfredo Camilo Carrillo Ortiz, alias Gocho, to Chile. Another defendant, Rafael Gámez Salas, alias El Turko, arrived in Chile from the United States the same day. In a related step months earlier, Colombia extradited Dayonis Junior Orozco Castillo, alias Botija, to Chile in July 2026 after a coordinated operation involving authorities from Colombia, Chile and Peru. Pérez Nieto is currently arrested in Colombia following the August 27 capture, as the joint investigation continues.
