In September 2009, several individuals fell under suspicion and were arrested due to fears that a suspected jihadist cell in New York was planning to explode bombs in the United States.
According to a July 2010 indictment, the cell had members in London plotting to carry out a companion bombing in the United Kingdom.
Zazi acknowledged receiving weapons and explosives training in Pakistan's semi-autonomous Federally Administered Tribal Areas.
Taxi driver Zarein Ahmedzay and Bosnian immigrant Adis Medunjanin were charged with making false statements to the police, and pleaded not guilty.
[11] The July indictment, noting Medunjanin called an operator and said "We love death", alleged that the crash was intentional and part of a suicide attack.
[7] Mohammed Zazi was charged on the counts of conspiracy to obstruct justice, as well as conspiring to dispose of his son's bomb-making materials and chemicals.
[18] He faced up to six months in prison, and as part of the plea arrangement the government agreed not to request any jail time.
Abid Naseer and Tariq Ur Rehman were charged with involvement in a companion plot in the United Kingdom.
[5][7] Naseer was already in custody after his arrest for sending e-mails to an al-Qaeda operative in Pakistan that were reported to be at the heart of a plot to bomb targets in north-west England.
Most of the evidence in his trial consisted of email exchanges between Naseer and an al-Qaeda handler who was directing plots to attack civilians in Manchester, New York City and Copenhagen.
It was the first terrorist trial to include documents recovered during the 2009 Navy Seal raid against Osama bin Laden’s compound.
