A law enforcement official says a Colorado air shuttle driver accused of a homemade-bomb plot against New York City flushed the explosive materials down the toilet.
Law enforcement officials tell The Associated Press that Najibullah Zazi (nah-jee-BOO'-lah ZAH'-zee) had told federal prosecutors he was armed with bomb-making materials when he drove to New York City last September.
But one official says that Zazi flushed the explosives down the toilet in New York after becoming concerned about a traffic stop.
The official wasn't authorized to speak publicly about the case and spoke to the AP on condition of anonymity.
Two law enforcement officials told The AP Zazi has agreed to enter a guilty plea Monday.
An official says Zazi reached the plea deal after cooperating with authorities.
