UPDATE: All Clear at Atlanta Journal-Constitution's Dunwoody Office

DUNWOODY, GA -- Police and hazmat units responded to a letter with a suspicious white powder inside at the Atlanta Journal Constitution's office in Dunwoody on Wednesday.

The powder was not found to be hazardous, after Dunwoody and DeKalb police, along with DeKalb fire units and an FBI hazmat team responded to the incident.

Authorities said the package appears to be similar to a letter received yesterday at the State Bar of Georgia's Marietta Street, Atlanta office.

The Georgia Bar Association letter tested negative for any bio hazards in the preliminary screening.

No one was evacuated from the building, but the building's ventilation system was shut down for a short period of time.
