Explosion outside New York federal building in Manhattan apparently caused by fireworks, sources say

An incendiary device went off outside a federal building in Lower Manhattan Monday morning and a suspect has been taken into custody, police sources said.

The incident happened outside 26 Federal Plaza, a building that houses dozens of agencies including the FBI, Immigration and Customs Enforcement, and U.S. Citizenship and Immigration Services. 

Preliminary information indicates fireworks in a garbage can exploded, senior security sources told CBS News. The fire department responded to put out flames, and a man was taken into custody. 

The sources said an initial review found no shots were fired.  

Police said people should expect traffic delays, mass transit disruptions and road closures near Worth Street and Lafayette Street. They are urging people to avoid the area.
