Officials: NY men under surveillance in terrorism investigation; more arrests expected

A “handful” of men in New York are possible associates of the chief suspect in a suspected plot to use homemade bombs to attack New York City commuter trains, and investigators have them under heavy surveillance, law enforcement officials said Wednesday.

Investigators are still hunting for additional players and expect to make more arrests than just the chief suspect, 24-year-old Denver airport shuttle driver Najibullah Zazi, according to an official who declined to discuss when that might happen or how many people are under scrutiny.
