The Social Security Administration office in Conway has been evacuated after a suspicious package was found, officials said.
Officials with the Horry County Bomb Squad determined the package was a three-ring binder with miscellaneous papers inside, said Catina Hipp, Conway police spokeswoman.
Bomb squad officials used a robot to take a photo of the package then determined it to be papers and the binder.
The package was delivered to the building on 1316 Third Avenue by the U.S. Postal Service and it's not clear why officials believed it was suspicious, Hipp said.
A security officer located the package and called police at 12:10 p.m., Hipp said. The building was evacuated at 1 p.m., Hipp said.
Officials from State Law Enforcement Division, Conway Police and Conway Fire Rescue also are at the scene.
