A bomb scare closed the Wauwatosa post office on Wednesday.

Police said an elderly customer came into the post office with a package around 11:30 A.M. and said it was a bomb.

Employees alerted authorities and then evacuated the building.

The bomb squad was called in.  They x-rayed the package and determined it wasn't a bomb.  The post office has since reopened.

The woman was arrested, but has not been charged.
