A bomb threat this afternoon cleared the Matthew J. Perry Jr. federal courthouse and surrounding streets in downtown Columbia for about two hours.
Bomb-sniffing dogs from SLED searched the three-story building and found no evidence of explosive, said Columbia Deputy Fire Chief Aubrey Jenkins.
Columbia fire trucks were among several agencies that responded to the possible threat.
Also on hand were officers from the FBI, the U.S. Marshall’s Service and the Columbia police department.
The threat was telephoned in to the clerk’s office.
The Perry courthouse, built in 2004, has security features that include strong fences around its perimeter, an ample setback from streets and tightly controlled access.
During today’s incident, occupants of nearby buildings were allowed to leave their offices but were not allowed back until things were ruled safe.
No further information was available at this time.
It was the second threat alert in two months.
On April 22, the courthouse was evacuated after employees screening a package found what they thought was a possible bomb. After security inspected the package, it was determined not to be a bomb, officials said.
