ARLINGTON, Va. (MILITARY TIMES/WUSA9) - A white, powdery substance was found Thursday morning in the mailroom of Naval Support Facility Arlington, Va., prompting the evacuation of about 800 people, a Navy official said.
Building 12 houses the mailroom and the offices of the chief of naval personnel, according to the official, who said the evacuations were a precautionary measure. Arlington County fire department and hazardous-materials officials, as well as Navy personnel, investigated.
At approximately 1 p.m., officials with the Navy said the suspicious letter tested negative for hazardous material, and the situation was cleared. The letter is now with Navy authorities. Personnel are now back in the building, according to authorities.
The incident comes just days after letters that tested positive for the poison ricin were mailed to President Obama and Sen. Roger Wicker, R-Miss, in Washington. The FBI arrested Mississippi resident Paul Kevin Curtis in connection with the letters Wednesday night, an FBI release said.
