WASHINGTON (Reuters) - A reportedly leaking, smelly package that forced an evacuation of the U.S. Federal Emergency Management Agency headquarters turned out to be a harmless computer mouse, a fire department official said on Monday.

Washington, D.C. fire department spokesman Alan Etter said investigators identified the object after about 200 FEMA employees were evacuated from the headquarters building.

The fire department was called to FEMA with a report of a leaky, odorous package. However, Etter said, upon investigating the suspicious envelope the department concluded, “It wasn’t leaking; it didn’t smell, and it had a computer mouse in it.”
