Four people, including the suspect, have been hurt following a pipe bomb explosion in a New York City subway at the height of the morning rush hour.
New York Fire Department officials said none of the injuries are believed to be life-threatening.
Police say the pipe bomb explosion inside the subway happened in an underground passageway between Seventh and Eighth Avenues on 42nd Street.
The explosion filled the passageway with smoke while it was crowded with throngs of Monday morning commuters.
A law enforcement official said the man had a pipe bomb strapped to him when it went off.
The person was arrested and has non-life-threatening injuries.
The Port Authority Bus Terminal, the nation's largest bus hub, was shut down, along with the eight subway lines and all streets around Times Square.
The explosion triggered a massive emergency response by police and fire both above and below ground, disrupting subway and bus services at the Port Authority.
Video from above the Crossroads Of The World showed queues of police and emergency vehicles, their lights flashing, lining the streets and no other vehicle traffic moving.
Everything around the Port Authority area was shut down, a surreal scene at what would ordinarily be a bustling rush hour.
New Jersey Transit buses heading to the Port Authority were diverted to other locations.
NJ Transit said buses were taking passengers to Secaucus and Hoboken, where they could take trains into the city.
White House Press Secretary Sarah Sanders tweeted that President Donald Trump had been briefed on the explosion.
