"They're still looking," a senior counterterror official told the Daily News. As to whether they have identified all the conspirators, "nobody knows the answer for sure," the official said.
FBI arrest documents showed prime suspect Najibullah Zazi, 25, an Afghan, visited the city from Colorado on the 9/11 anniversary carrying a laptop with bomb-making notes he wrote. Specific attack plans or targets remain unknown, a Justice Department statement said.
Zazi was collared in Aurora, Colo., near Denver, by the FBI on Saturday night and was charged with lying about the bomb notes. He'll likely soon be slapped with tougher terrorism charges, sources said.
The senior official said the feds believe the plot is now "compromised" and would be "hard to bring forward."
"We think we have a pretty good handle on the threat, but we'd know a lot more if Afzali hadn't tipped them in the beginning," another insider said.
The source added that court papers released yesterday reveal only a "sliver" of the conspiracy.
"The FBI is investigating several individuals in the U.S., Pakistan and elsewhere, relating to a plot to detonate improvised explosive devices in the U.S.," the Justice Department said.
The Zazis will appear in court today in Denver as Afzali comes before a federal judge in Brooklyn.
The FBI said Zazi admitted last week that Osama Bin Laden's goons trained him in "weapons and explosives" last year at an Al Qaeda camp in Pakistan's war-torn Pashtun tribal areas, prosecutors say.
