NEW YORK — Federal authorities expect to file more charges in an alleged plot by an al-Qaeda associate to attack New York City with homemade bombs, a prosecutor said Thursday.
Assistant U.S. Attorney Jeffrey Knox told a judge that the charges would be contained in a new indictment against Najibullah Zazi, a Colorado airport-van driver arrested earlier this year on charges of conspiring to use weapons of mass destruction.
“I think it’s likely there will be additional charges,” Knox said at a pretrial hearing in federal court in Brooklyn. “The investigation continues.”
The prosecutor didn’t specify the charges or say whether the indictment would name more defendants. He called the evidence in the case “voluminous.”
Zazi, who sat motionless at the defense table during the 15-minute hearing, was ordered to return to court Feb. 16.
“He’s in fairly good spirits, considering his situation,” defense attorney Michael Dowling said afterward.
Authorities allege that Zazi, who received instructions on explosives at an al-Qaeda training camp in Pakistan, bought beauty supplies in Aurora to make peroxide-based bombs. They say he urgently tried to mix up explosives in a hotel room in early September, and then drove to New York to carry out an attack, possibly on the New York transit system.
Investigators, who had Zazi under surveillance, searched his rented vehicle in New York on Sept. 10 and found a laptop computer with bombmaking instructions, authorities said. They impounded the vehicle.
Fearing he was being watched, Zazi flew back to Denver on Sept. 12, authorities said. He was arrested a week later.
