Bomb technicians deemed a suspicious package report at a mail facility in northeast Washington to be non-threatening. It was the same facility where a package ignited last week , according to D.C. police.
Investigators were aware of the suspicious package report, said Richard J. Wolf, a spokesman for the FBI's field office.
The suspicious package was reported Wednesday afternoon, D.C. police spokeswoman Istmania Bonilla said. D.C. Fire and EMS assisted the investigation.
On Friday, a suspicious package addressed to Secretary of the Department of Homeland Security Janet Napolitano ignited at the facility in the 3300 block of V Street NE. The piece of mail flashed, popped, ignited, smoked and quickly went out, police said. No one was injured.
The mail that the facility handles includes government mail.
The previous day, two similar pieces of mail flared up at state government buildings in Maryland, causing minor injuries. A package addressed to Gov. Martin O'Malley at the Jeffrey Building in downtown Annapolis -- where mail for the governor is screened -- included a note reading, "Report suspicious activity. Total [expletive]. You have created your own self-fulfilling prophecy." The second package, addressed to Maryland Department of Transportation Secretary Beverly Swaim-Staley, ignited at the Harry Hughes Department of Transportation Building in Hanover.
