Hazardous materials crews have been called to
an Internal Revenue Service building in Ogden, Utah.
Media reports said a suspicious substance was found in the building Monday and that part of it was evacuated while other parts were locked down.
The FBI was involved in the investigation but said it didn't
have any information to release. The Weber County sheriff's office said it did had no information on the incident.
The two- or three-story building is in an industrial area and is surrounded by a fence in Ogen, about 35 miles north of Salt Lake City.
No signs on the building indicate it is an IRS facility.
