An explosive device destroyed a mailbox at the Lorton home of the Treasury Department’s inspector general Monday, authorities said.
The Bureau of Alcohol, Tobacco, Firearms and Explosives and Fairfax County police and fire officials are investigating the incident at the home of Eric M. Thorson, and they have removed evidence to be analyzed at a lab, authorities said. No one was injured.
“Pieces of the mailbox and pieces of the device were found around the area,” said Richard Delmar, counsel to Treasury’s inspector general.
Delmar said Thorson was home at the time of the bombing, which a Fairfax police spokesman said probably occurred between midnight and 12:30 a.m. New Year’s Eve. County police were called to the scene about 9 a.m. that day.
Delmar said the explosive device appeared to be a pipe bomb. He said officials have no reason to suspect that the bombing was linked to Thorson’s work at the Treasury Department.
Authorities declined to provide more details about the bombing because the investigation is continuing.
Thorson was nominated to his post by then-President George W. Bush and was confirmed in 2008. His office does investigations and audits of Treasury Department programs, and it reports to the Treasury secretary and Congress.
