Explosion Rocks Manhattan, one person in Police custody

A suspect is in custody after an "attempted terrorist attack" underneath the Port Authority bus terminal in New York City today, sending rush-hour commuters scrambling to evacuate near the busy transit hub just blocks from Times Square, New York City Mayor Bill De Blasio said.

Authorities called the explosive an "improvised low-tech explosive device" that was held on the suspect with Velcro and zip-ties.

The 27-year-old suspect, Akayed Ullah, was badly injured in the arm and torso from the explosion that went off in his arms, sources said. He is alert and conscious and was taken to a hospital, sources said. The suspect, originally from Bangladesh, has been in the United States for seven years and has an address in Brooklyn, sources said.

The explosive detonated in the subway in a passageway between 42nd Street and 8th Avenue and 42nd Street and 7th Avenue. New York Gov. Andrew Cuomo said hearing of a bomb in the subway is "one of our worst nightmares."

Christina Bathea, 29, told ABC News she was in the passageway on her way to work next to the terminal when she heard a bang, saw smoke and ran.

"If I didn’t believe in God, I believe in God today," she said, adding that she commuted from Yonkers, New York.

Three people were injured, but none of their wounds appear to be life-threatening, the FDNY said.

The explosion occurred at about 7:20 a.m. The terminal was temporarily closed and has since reopened. Subways were bypassing the terminal and Times Square stations.

President Donald Trump was briefed on the incident, White House Press Secretary Sarah Sanders said
