The suspect in the incident at the Port Authority Bus Terminal, a block from Times Square, was identified as Akayed Ullah, the New York Police Department commissioner said. The suspect had burns and lacerations while three other people, including a police officer, had minor injuries.

The weapon was based on a pipe bomb and was fixed to the suspect with zip ties and velcro, police said. New York Governor Andrew Cuomo, speaking at a news conference near the site, described the device as “amateur level.”
