A newly unsealed U.S. indictment accuses former Venezuelan President Nicolás Maduro and his wife, Cilia Flores, of conspiring to use torture and other abuses to preserve his grip on power. The revised indictment, unsealed Thursday in New York, alleges that people acting for the government Maduro led harassed, arrested, assaulted, tortured or killed thousands of Venezuelans. It describes electric shocks, beatings and asphyxiation, and says Maduro approved torture methods and threatened to kill a prisoner’s child as psychological intimidation. The allegations have not been proven in court. The filing also says three U.S. citizens were among the alleged victims, though it does not identify them. One was allegedly beaten, shocked and forced to eat his own vomit during eight months in detention. Another was badly beaten and had a gun put in his mouth. A third was allegedly hooded, handcuffed and beaten repeatedly over two days, leaving a permanent eye injury. The indictment cites Venezuela’s military intelligence agency, DGCIM, which was led for years by Gen. Hugo Carvajal, a co-defendant who later broke with Maduro. Carvajal pleaded guilty to drug-trafficking charges in New York last year and has offered to testify against Maduro, according to the filing’s background. Maduro and Flores have been held in New York since U.S. forces seized them during a raid at their Caracas home in early January. They have pleaded not guilty to an existing U.S. case accusing them of joining a conspiracy to bring cocaine into the United States. Both have denied wrongdoing, and Maduro has faced a years-long International Criminal Court investigation over alleged crimes against humanity related to his government’s crackdown on opponents. Flores appeared in court Thursday as her lawyers sought her release to house arrest, citing heart problems and other medical concerns. Her attorneys said she has lost 25 pounds in custody, may need heart surgery and could be monitored around the clock at a New York residence. They also said she was injured during the operation in which she was captured. Prosecutors opposed release, arguing Flores would pose an extreme flight risk and danger to the public. Her lawyer said he had not yet had time to review the new allegations. The couple’s attorneys have also argued that they are entitled to immunity as the leaders of a foreign country. Maduro served as Venezuela’s president from 2013 until his capture. The Trump administration has described the raid as a law-enforcement operation, while Maduro has called himself a prisoner of war and his capture a kidnapping.
