A homemade explosive was found at a Harlem train station, and one man has been taken into custody.
The device, found in front of a ticket window at Metro-North's 125th Street station, consisted of fireworks taped together with 30 bullets, metal objects and a fuse in a bag -- and was capable of igniting, authorities said.
Officials said people could have been killed or injured.
A police explosives squad removed the device and authorities restored train service to the station.
They say a 57-year-old man with no legs in a wheelchair left the would-be bomb. He was taken into custody and is now under observation at Bellevue Hospital Center. Police questioned and released one man who was with him and are still searching for another.
Law-enforcement sources said the suspect in custody has past drug arrests and says a woman gave him the bag.
Authorities say they do not suspect terrorism was a motive but the investigation continues.
