Authorities also found a passport in Ullah's name with the handwritten notation: "O AMERICA, DIE IN YOUR RAGE".
Addressing reporters today, Ullah's attorney Amy Gallicchio emphasized the importance of due process.
"Less than one month ago, during the holiday rush hour, Akayed Ullah allegedly detonated a bomb in a major transit hub of New York City", U.S. Attorney Geoffrey S. Berman said in a press release. U.S. Magistrate Judge Katherine Parker is pictured at left on the bench beside the video monitor.
The Bangladeshi man accused of attempting a suicide bombing in a busy New York City commuter hub in the name of Islamic State in December was indicted on US terrorism charges by a grand jury on Wednesday.
Ullah could face life in prison if he is convicted of all charges in the attack. Only he was seriously injured.
When Manhattan Federal Judge Richard Sullivan asked Ullah his plea, Ullah replied, "At this moment, not guilty". Ullah posted on Facebook earlier in the day of the attack, "Trump you failed to protect your nation", according to a criminal complaint.
