RALEIGH (AP) -- Once again, workers at John Edwards' campaign headquarters in Chapel Hill have had to evacuate the building because of a suspicious package.
A beeping device inside a package sent to the Democratic presidential candidate forced the third evacuation this year.
Captain Bob Overton of the Chapel Hill Police Department says a bomb squad from nearby Durham County made the device safe, but authorities weren't immediately sure if the item posed a threat.
Edwards officials say the package arrived at campaign headquarters this morning.
Postal employees in Chapel Hill intercepted another suspicious package in May after finding it contained a powdery substance. Edwards staffers also evacuated their office in Chapel Hill in March after an employee opened a package that contained a powdery substance and what Edwards later deemed "negative comments."
Both packages tested negative for anthrax.
