Reporting from Washington and New York - A federal grand jury in New York indicted a Denver man on a terrorism charge Thursday after federal authorities alleged that he and possibly three others had gone on a buying spree of bomb-making chemicals and were preparing an attack on U.S. soil.
The one-count indictment alleges that Najibullah Zazi, 24, worked for more than a year on a plot to detonate a weapon of mass destruction.
Justice Department documents did not name the alleged co-conspirators, but said that three other Denver-area residents had bought unusual amounts of chemicals from beauty-supply stores, including hydrogen peroxide and acetone, which can be used to make explosives.
In all, authorities are searching for at least a dozen people for questioning in what they describe as the first Al Qaeda-linked plot on U.S. soil since the Sept. 11, 2001, terrorist attacks.
"Zazi remained committed to detonating an explosive device up until the date of his arrest" last Saturday evening, nine days after he arrived in New York City, allegedly to meet with others involved in the plot, according to a Justice Department document.
The document was part of a motion also unsealed Thursday to keep Zazi detained in Colorado without bail. A federal judge agreed, setting the stage for Zazi's transfer to New York to face the terrorism charge.
