Mexico City (CNN) -- The United States has extradited a suspected leader of the Sinaloa cartel to the United States, Mexico's attorney general's office said Wednesday.
Jesus "El Rey" Zambada Garcia left Mexico on Tuesday afternoon and was handed over to U.S. authorities in New York City later that day, sources from the attorney general's office said.
He was arrested in October 2008 in Mexico City and has been indicted in New York on drug trafficking and conspiracy charges for his alleged role in transporting thousands of kilograms of cocaine.
Last month, the U.S. Department of the Treasury added him to its drug kingpin list, describing him as a "key Sinaloa cartel operative" who "controlled a narcotics trafficking route via the Mexico City International Airport on behalf of his brother."
His brother, Ismael "El Mayo" Zambada Garcia, is on Mexico's list of most wanted criminals and is believed to be one of the cartel's principal leaders.
U.S. investigators are also offering a $5 million reward for information leading to the brother's arrest.
