A busy stretch of downtown Decatur was shut down for much of Thursday after a suspicious substance was discovered at the DeKalb County Public Defender’s Office.

After nearly six hours of investigation, the mystery powder turned out to be nothing more than crushed candy, authorities said.

Nearby businesses and offices were evacuated shortly after noon when a suspicious package was located inside the building, Decatur Fire Chief Toni Washington said.

Decatur police said an employee picked up a stack of mail and noticed a white powdery substance fall out of an envelope.

“After noticing the unknown substance, she removed the envelopes from her desk, placed them in a plastic bag and emergency personnel were called,” Decatur police spokeswoman Capt. Jennifer Ross said.

Traffic on Church Street was shut down between East Trinity Place and Sycamore Street for most of the day as DeKalb’s bomb unit and hazardous materials team responded to the scene in boots and large rubber suits.

The area reopened shortly before 6 p.m. once officials determined the package was not an explosive device.

“Further investigation revealed loose candy had been mailed and was crushed during transit, resulting in the substance observed spilling from the mail,” Ross said.

After standing outside for hours in the cold, employees from nearby businesses and restaurants that were evacuated during the investigation were allowed to return to work, authorities said.

Channel 2?s Christian Jennings went to the scene where she found several emergency vehicles had blocked off the area.
