A "handful" of men in the city are reportedly under heavy surveillance as possible associates to terror suspect Najibullah Zazi.
Law enforcement officials told the Associated Press today that investigators expect to make more arrests, but they say the men are no longer a threat since the plot was thoroughly disrupted.
The FBI had no comment on the report of pending arrests.
Authorities have said three people traveled from the city to Denver over the summer and used stolen credit cards to help Zazi buy ingredients normally used in homemade bombs. They returned to the city, but have not been publicly accounted for.
Zazi pleaded not guilty on Tuesday to conspiring to use weapons of mass destruction.
Zazi's father and a Queens imam have pleaded not guilty to lying to federal officials. Neither faces terrorism charges.
