A caller reported a bomb threat at Bell County Courthouse Thursday morning, leading to Main Street and Central Avenue being blocked off.

The caller gave a specific time of detonation for a bomb reportedly located in a courtroom on the fourth floor of the building.

A search of the building failed to reveal any suspicious devices, but the courthouse was evacuated until the reported detonation time had passed.

Central and Main were closed in a two-block perimeter, and remained closed until the threat was cleared.
