New York City police have launched an investigation into suspicious white powder found in envelopes at American Express’ headquarters near the site of the September 11, 2001 terror attacks.
Detective Mindy Diaz said no injuries were reported after police were called to the building in lower Manhattan. She said three people were exposed to the powder, which authorities were testing.
In October and November 2001, five people were killed after coming into contact with post containing anthrax and at least four UN foreign missions have received packages containing suspicious powder.
