NEW YORK — A man detonated an improvised explosive device in an underground passageway at a major commuter hub in New York City Monday morning, officials said. New York Police Commissioner James O’Neill identified the suspect as Akayed Ullah, 27, who sustained injuries from the blast and was in police custody.
New York Mayor Bill de Blasio said the incident was an attempted terror attack.
The underground passageway connects the subway stations at Times Square and the Port Authority Bus Terminal and would have been packed with commuters during the morning rush.
O’Neill said three other people in the immediate area of the blast were also injured.
CBS News has learned that the suspect was from Bangladesh and had a second device.
Some passengers were evacuated as a precaution.
White House press secretary Sarah Sanders said that President Trump had been briefed on the incident.
People reported seeing the bomb squad responding to the incident and posted images of the scene on social media.
The explosion has led to delays along some of the subway lines that pass beneath the bus terminal. Many subway lines were forced to bypass the area.
New Yorkers were advised to avoid the area.
