Atlanta Building Evacuated Over Glass Egg

Last Updated 2:32 p.m. ET

Police say they evacuated a federal building in downtown Atlanta and sent in the bomb squad after a suspicious package was found.

A fire alarm went off, nearby streets were closed and a daycare in the Peachtree Summit Federal Building was emptied after mailroom workers X-raying packages saw one they thought was suspicious.

CBS affiliate WGCL reports that what had been reported to be a grenade turned out to be a glass egg.

The scare sent workers streaming onto the sidewalks and brought fire trucks and police cars to the building. Members of a bomb squad put on their bulky suits to investigate while evacuated workers milled around.

Workers who spent more than an hour on nearby sidewalks were allowed Tuesday afternoon to go back into the 31-story building that sits at a busy intersection and overlooks the interstate. Daycare workers were seen rolling cribs full of small children back into the building.

"It was scary. We were just doing our daily routine when we saw people start evacuating, and the fire alarm went off. They told us it was a bomb threat," said Marie Manley, 38, a management analyst for the U.S. Social Security Administration.

It is routine to X-ray packages that come into the mail room of the building which houses several federal agencies, including the Internal Revenue Service.

The building also sits adjacent to a station of the Atlanta underground transit system, as well as a hospital.
