Ullah, a Bangladeshi immigrant, was the most severely injured person from the attack in the bombing of a heavily-trafficked underground walkway connecting the Port Authority bus terminal with the subway.
Akayed Ullah was arrested after allegedly setting off a pipe bomb in a tunnel leading to Times Square on December 11, 2017. The attack injured at least four people plus the suspect, who suffered burns and wounds to his abdomen and hands.
Prosecutor George Turner said prosecutors had gathered materials for the case including surveillance videos, photos from the crime scene, DNA evidence, statements that Ullah made to officials after his arrest, postings from his social-media accounts, e-mails, MetroCard data, and phone records.
The attack took place in a tunnel that connects the Port Authority Bus Terminal and the Times Square subway stations. Inside Ullah's passport, which was recovered from his home, was a handwritten note that read, "O AMERICA, DIE IN YOUR RAGE", according to the complaint.
