Akayed Ullah, a 27-year-old Bangladeshi man, faces a number of federal and state terrorism charges after he allegedly detonated a device made of a battery, wires, metal screws and a Christmas tree lightbulb during the busy morning commute on Monday.
Five people were treated for minor injuries at area hospitals, while the suspect was said to be seriously injured.
In an interview with investigators, Ullah admitted that he built and detonated the device and said he was inspired to do so by ISIS.
"I did it for the Islamic State," Ullah told investigators, according to the federal complaint.
He faces five federal terrorism-related charges and three state terrorism-related charges, according to court documents.
