NEW YORK AP – A former prosecutor says authorities’ refusal to discuss the whereabouts of three people alleged to have helped a suspected al-Qaida operative buy beauty supplies to make explosives might mean the accomplices have left the country or are secretly cooperating.

The suspect, Afghan immigrant Najibullah Zazi, pleaded not guilty Tuesday to plotting a bomb attack in New York. Police Commissioner Raymond Kelly pronounced the threat neutralized and said there is nothing to fear from Zazi’s three alleged accomplices.
