NEW YORK (AP) — A law enforcement official says what is believed to be an explosive device has been set off on Manhattan subway platform.

The explosion happened around 7:30 a.m. Monday. Details were still developing.
A person was arrested and one has non-life-threatening injuries. There was no immediate word of any other injuries.

The official spoke to The Associated Press on condition of anonymity because they were not authorized to speak publicly about the incident.

Passengers were evacuated as a precaution from the subway line where the explosion happened, near 40th Street and Eighth Avenue.
