Two law enforcement officials said the suspect is of Bangladeshi descent and has a Brooklyn address, while NYC Mayor Bill de Blasio declared the blast an act of terror at a late-morning news briefing, saying, "Thank God the perpetrator did not achieve his ultimate goal."
A law enforcement source said officers took down the suspect, believed to be a man in his 20s and the only person involved in the attack, cuffed him and brought him to a hospital with a serious stomach laceration. Three other people were hurt but are expected to be OK, authorities said.
The FBI's Joint Terrorism Task Force has responded, and the White House says President Trump has been briefed on the situation.
