An employee for BioLab may face arrest for calling in a fake bomb threat on the company Wednesday afternoon.

According to Rockdale County Sheriff's Office (RCSO) Cpl. Michael Camp, on Wednesday, just before 5 p.m., someone called 911 and told dispatchers using a "muffled" voice that there was a bomb in the BioLab building set to go explode in three hours.

Using its K-9 units, the RCSO searched the entire building of BioLab for about an hour, but no bomb was found on the scene

The RCSO traced the call to a current BioLab employee's phone. The employee was detained at BioLab while he was in the middle of his work shift around 5:15 p.m. and taken to the RCSO headquarters, says Camp.

"The whole thing took about 20 minutes," he said.

The male long-term employee denied making the call and told deputies someone else could have made the call from his phone.

The case is until under investigation.

If arrested, the employee could be charged with making terroristic threats.
