The Carbon County courthouse buildings in Jim Thorpe were cleared Wednesday afternoon after a bomb threat was called in.

The threat was later found to be unfounded.

Commissioners’ Chairman Wayne Nothstein said that a call came in to the sheriff’s office around 3:30 p.m.

Employees were evacuated and security protocols were put into place.

Some businesses around the courthouse and administration building were closed Wednesday evening as a result of the police activity.

Jim Thorpe police secured the area while the investigation took place.

The Pennsylvania State Police Bomb K-9 Unit completed its sweep of the courthouse and administration buildings just after 6 p.m.

Sheriff Anthony Harvilla said that nothing was found in the buildings, adding that the sheriff’s office will maintain heightened security at the offices for the remainder of the week.

District Attorney Michael Greek is investigating the cause of the threat.
