Colombian security forces captured a suspected senior leader of the Venezuelan gang Tren de Aragua, the U.S. Southern Command announced on Friday (August 28, 2026), hailing the arrest as a result of stronger military cooperation between the historically close allies.
The capture on Thursday (August 27) of Luis Saúl Pérez Nieto, who Colombian authorities described as having coordinated the gang’s weapons and drug-trafficking networks across the region, offers an early sign of how rapidly the two countries have intensified their joint efforts against organised crime under Colombia’s new conservative president, Abelardo de la Espriella.
An admirer of U.S. President Donald Trump, de la Espriella came to power earlier this month promising to crush his country’s powerful drug traffickers with help from Washington. His government has named Medellín, Colombia’s second-largest city, as the hub of Mr. Trump’s new regional anti-cartel alliance and welcomed joint operations with the U.S. military on Colombian soil in a sharp break from his progressive predecessor.
“Narco-terrorists have no haven in our hemisphere,” the U.S. Southern Command said in its statement on Friday (August 28) announcing the capture of Pérez Nieto. “We stand united with our partners to dismantle these criminal networks and protect our homeland.”
Pérez Nieto, known by the aliases “Páez” and “Nairobi,” was captured in an operation that also involved the U.S. Drug Enforcement Administration (DEA), Colombian police said, without elaborating.
Colombian police accused Pérez Nieto of leading the expansion of Tren de Aragua in Peru while coordinating drug and arms trafficking across the continent, helping transform what began as a prison gang operating from Venezuela’s Tocorón penitentiary into a transnational criminal syndicate.
In 2023, Pérez Nieto escaped from that prison along with his close confidant, the gang’s leader, Héctor “Niño Guerrero” Guerrero Flores, Colombian police added. Guerrero Flores was killed in a U.S. military strike in a rare collaboration with Venezuela earlier this year.
The Trump administration last year designated Tren de Aragua a foreign terrorist organisation, part of its effort to treat Latin American cartels as national security threats rather than conventional criminal groups. However, Mr. Trump has at times overstated the gang’s connections in an effort to justify deporting Venezuelans, The Associated Press previously reported.
“Congratulations to President Abelardo de la Espriella and the Colombian National Police on the capture of Luis Páez Nieto, a senior Tren de Aragua leader,” DEA Administrator Terry Cole said.
Colombian and Peruvian authorities said the U.S. had requested Pérez Nieto’s arrest and extradition on charges of terrorism, money laundering, drug trafficking and criminal conspiracy. The Trump administration has not publicly detailed the case against him. The DEA did not respond to questions about the charges against Pérez Nieto in the U.S. or its role in the operation.
Earlier this week, U.S. Southern Command chief Gen. Francis Donovan met Colombia’s Defence Minister and military leaders in the port city of Tumaco before travelling to Ecuador for regional security talks focused on the volatile border between the two countries, rife with drug smuggling, illegal mining and human trafficking.
During his visit, Donovan said that U.S., Ecuadorian and Colombian officials had agreed on a strategy to “hunt cartel leadership, shatter their logistics and permanently deny them safe haven.”
“The border between Colombia and Ecuador is a geographic chokepoint that violent cartels have long exploited,” he said. “Today, we are changing the game.”
Colombia and Ecuador are among the few regional governments that have agreed to allow joint operations with U.S. forces against criminal groups on their territory, part of the Trump administration’s efforts to extend its lethal campaign against suspected drug smuggling boats to land.
It comes as South American voters increasingly elect Mr. Trump-aligned conservative leaders who have called for far-reaching security crackdowns.
Among them is Chilean President José Antonio Kast, whose government has struggled to deliver on its sweeping promises to curb crime and carry out and mass deportations.
But on Friday (August 28), Chilean officials celebrated a victory as they announced the arrival of two alleged Tren de Aragua leaders extradited from the U.S. and Colombia to face charges in Chile related to the abduction and killing of former Venezuelan army Lt. Ronald Ojeda in 2024. The body of the Venezuelan dissident, who had sought political asylum in Chile, was found inside a suitcase buried beneath a cement slab in Santiago, the capital.
Chilean authorities have charged Rafael Enrique Gámez Salas, the alleged leader of Los Piratas, the main branch of Tren de Aragua in Chile, with kidnapping, extortion and criminal association, among other offenses.
The other suspect, Alfredo Camilo Carrillo Ortiz, alias “El Gocho,” was extradited from Colombia. Chilean prosecutors accuse him of helping plan and carry out the killing and running the informal settlement where Ojeda’s body was buried.
Chile’s undersecretary for public security, María del Pilar Giannini, called the extraditions “a concrete demonstration” of the Kast government’s crusade against organised crime. “We are going to pursue them to the very end,” she said.
U.S. officials praised Gámez’s extradition from California, where he was serving a federal prison sentence for illegally reentering the country. Attorney General Todd Blanche called it “evidence of the strong cooperation with our Chilean partners to combat transnational crime, dismantle foreign terrorist organisations like Tren de Aragua and hold members accountable for their heinous criminal acts.
