Investigators probing the deadly New Year

ISIS-inspired Akayed Ullah set off a pipe bomb that partially exploded in New York City’s busiest subway station in 2017.

The device targeted the pedestrian tunnel between Times Square and Port Authority stops in Manhattan.

Ullah was arrested after his bomb failed to fully explode, leaving him with serious burns. The blast spread panic but caused only minor injuries to three people near him. 

After growing angry at American foreign policy in the Middle East, Ullah grew consumed by online Islamic State propaganda “glorifying brutally violent stabbings, shootings, and bombings targeting Americans,” prosecutors argued in federal court in Manhattan.
