Hazardous materials crews and the FBI were on the scene Monday at the IRS building in Ogden, Utah, where several people were subjected to decontamination showers.
Two people were taken out of the building on stretchers for "medical emergencies," but their conditions "do not appear to be related to this incident," said the the FBI, which is leading the investigation. It released no further details.
The IRS confirmed that "an unknown substance" was discovered but also gave no further details. Local news reports suggested that a suspicious white powder may have been found in mail delivered to the facility.
Initial reports said the buiding was in Farr West, a small community near Ogden, but the IRS specified that the incident took place at the IRS campus on Rulon White Boulevard in Ogden, about 30 miles from Salt Lake City.
The incident began about 12:30 p.m. (2:30 p.m. ET) Monday, 11 days after a Texas man embroiled in a years-long dispute with the IRS crashed his small plane into the agency's complex in Austin, Texas.
