A 27-year-old man was in custody on Monday after detonating an explosive device on the New York City subway during the morning commute.

The suspect, Akayed Ullah, was one of four people injured in the explosion, which occurred at about 7.20am in a passageway near 42nd Street and 8th Avenue, in midtown Manhattan near Times Square, reported the Guardian citing the New York City police.

None of the injuries were life-threatening.

At a midtown press conference, New York police commissioner James O’Neill said the suspect had “an improvised low-tech explosive device attached to his body”.

He sustained burns to his hands and torso while the other three people suffered “ringing ears and headaches”.
 
"Terrorists won't win," Mayor Bill de Blasio said after a blast at the Port Authority terminal in Manhattan during the morning rush hour on Monday, reported BBC.

Mayor De Blasio said nearby subway stations were evacuated, and the Port Authority Bus Terminal shut down.

Police and fire crews blocked off the streets near the New York Port Authority in New York City, the report added.
