A bomb squad removed a suspicious device from the Jacksonville, Florida, city hall Tuesday, officials said.
The building was evacuated while the device was placed into a containment vehicle and safely transported to a sheriff department range, Sheriff John Rutherford said at a news conference Tuesday morning. The device - which had not been confirmed to be a bomb - would be blown apart and examined there, he said.
Workers were not allowed back into the building while bomb technicians completed a search for possible secondary devices, Rutherford said.
Mayor Alvin Brown said he was not in the building when the device was discovered by a security X-ray machine.
City officials said the evacuation would not disrupt preparations for Hurricane Irene, which is forecast to brush by Florida later this week.
