Four police officers with the Port Authority of New York and New
Jersey who were first on-scene after a man partially detonated a bomb in
a commuter passageway stopped him as he fumbled with his cell phone.
Officers Sean Gallagher, Drew Preston, Jack Collins and Anthony
Manfredini rushed to the area where Bangladeshi immigrant Akayed Ullah
was on the ground injured after attempting to set off an improvised
explosive device, investigators said.
