Former Venezuelan President Nicolás Maduro, in U.S. detention since his capture by the U.S. military in January, now faces additional charges including alleged torture, according to a federal indictment unsealed Thursday.

Maduro had already been charged with participating in a conspiracy to send cocaine into the U.S. The new indictment also includes charges of alleged human rights abuses during his reign as president of the oil-rich South American country, according to the Associated Press. 

Maduro and wife Cilia Flores, were taken from their Caracas home in a middle-of-the-night raid. They have pleaded not guilty in the criminal case first brought against them and co-conspirators years ago, the wire service also reports.
