Six offices of the U.S. Department of Agriculture were shut down Aug. 30 after receiving anonymous email threats of an undisclosed nature.
The offices are located in five states: Hamden, CT; Beltsville, MD; Raleigh, NC; Kearneysville and Leetown, WV, and Fort Collins, CO. The Colorado facility houses the U.S. Forest Service office, which operates under the auspices of the USDA and which employs more than 1,000 persons.
On Wednesday, Aug. 31, the federal agency announced it was reopening some offices under heightened security. Others remained closed until improved security measures could be implemented.
While the exact threats were not made public, a USDA spokesperson said worker and building safety were referenced in the multiple emails.
