1 Suspect In Custody, 4 Injured After Explosion At Subway Station In Midtown Manhattan

New York City police say a suspect is in custody following an explosion early Monday at a subway station a block away from Times Square. The fire department says four injuries were reported and that "all injuries are non-life-threatening."

"It was an effectively low-tech device," New York Gov. Andrew Cuomo said during a news conference near the site of the blast, after calling the news of an explosion "very disturbing."

Calling a bomb in a crowded subway "one of our worst nightmares," Cuomo said that the reality of what had occurred turned out to be better than what had been first feared.

Police initially said the male suspect was the only person injured in the incident at 42nd Street and 8th Avenue, site of the Port Authority bus terminal and subway stop. But the New York City Fire Department later provided an update to confirm the additional injuries.

Authorities haven't announced what caused the explosion. The Associated Press reports that "Law enforcement official tells AP that man had explosive device strapped on when it exploded in New York City subway," though that hasn't been officially confirmed.

"This was an attempted terrorist attack," de Blasio said. "Thank God the perpetrator did not achieve his ultimate goals. Thank God our first responders were there so quickly, to address the situation. He later said that "at this point in time, all we know of is one individual" carrying out what he called a failed attack.

Shortly before 8 a.m. ET, police said a blast was reported at the Port Authority bus and subway station in Midtown. The NYPD said that in the city's subway system, "The A, C and E line are being evacuated at this time."

The Port Authority issued a tweet saying, "The Port Authority Bus Terminal is open. Due to police activity, the entrance to the subway at the Port Authority Bus Terminal on Eighth Avenue is closed."

New York Mayor Bill de Blasio's office says that he has been briefed about the incident, adding, "The NYPD, FDNY and first responders are on the scene."

President Trump "has been briefed on the explosion in New York City," White House Press Secretary Sarah Sanders said via a tweet.
