A police sergeant sent an email to the building’s employees, telling them to avoid the area. Several officers and other workers congregated outside of the building. Other workers left the area entirely. However, people could be seen walking back into the building at about 11:30 a.m. on Monday morning.

The department’s bomb squad attempted to inspect the package. Photographs show heavily protected officers looking over some sort of object on the ground near a doorway. A high-ranking official said that the material inside “doesn’t appear to be serious.” Blankenbaker confirmed that the clear liquid turned out to be water.

As a precaution, both Lamar Street and Belleview Street surrounding the police building were blocked, but all roadways have since been opened back up to regular traffic. The note has police officials believing that this package was intended to be some sort of hoax. The incident remains under investigation.
