Yes, in Robertson County, Tennessee

As reported in the RCT:

A bomb threat briefly emptied the Robertson County Office building just before 2 p.m. today.

The Robertson County 911 Center was advised by Sumner County that they had received the threat from an untraceable cell phone number and that the link was traced to a cell tower in Sumner County. The caller said the bomb was in General Sessions Court in Robertson County.

Robertson County Sheriff's Office Captain P.R. West had the building sealed and searched before allowing people back in. The search was done quickly and efficiently, and turned up no indication of explosives.

General Sessions Judge Burton Glover wanted to continue with his court docket and once the building was declared safe, people filed back in to offices and courtrooms to resume schedules that had been interrupted.

Additional details will be posted as they become available.

All I could add is a little perspective as someone who was there for the afternoon court docket: It was brief disturbance that was handled with efficiency and professionalism
I appreciate the professional nature of the court officers, Springfield Fire Department and Robertson County Sheriff's Department. Without them, a troubling and confusing affair could have devolved into something that much more perilous.
