According to police scanner reports, seven people have been quarantined after being exposed to a "suspicious substance" during a "white powder incident" in a Lower Manhattan office building. At some time before 2:40 pm, a white powder was reportedly discovered inside an envelope at 26 Federal Plaza, a building that houses offices for the FBI, the US Citizenship and Immigration Services, the Environmental Protection Agency, the federal Department of Transportation, the Army Corp. of Engineers, and the Social Security Administration, among other groups. Early dispatches indicate the powder was found on the 40th floor, though later reports say it was discovered on the 14th floor.

Last fall, an envelope with a suspicious white powder was sent to the NY Times and another was sent to Reuters. Update: We're hearing there's now a "full hazmat response" at the WSJ offices and decontamination is being set up for people exposed on floors 9 through 11. more ›
