The accused ringleader of a plot to bomb New York transit systems is being arraigned in New York City on Tuesday.
    
Najibullah Zazi, a former airport shuttle van driver, is being charged with conspiring to use weapons of mass destruction. The 24-year-old Afghan immigrant has denied any wrongdoing.

"I'd like to stop this rush to judgment because what I've seen so far does not amount to a conspiracy," said Zazi's attorney, J. Michael Downing.

Zazi is accused of training with al Qaeda.

Investigators also say he was plotting to use common household chemicals to create bombs, similar to the ones used in the London and Madrid attacks. 

According to Assistant U.S. Attorney Timothy Neff, Zazi was engaged in "a chilling and disturbing sequence of events."

Neff said the sequence "suggests the defendant was intent on making a bomb and being in New York on 9/11 for purposes of perhaps using such item."
    
A law enforcement official says authorities now know the identities of three other people believed to be in on the scheme.
