Part of the Scott & White Health Plan office building in Temple was temporarily locked down Wednesday after someone called in a threat.

Police were dispatched to the building at 1206 West Campus Drive shortly after noon. Employees said they received a call from a man threatening to enter their office with a gun and open fire. As a precaution, portions of the building were locked down until police determined that it was safe for them to reopen.

The incident remains under investigation.
