A sweep of Chestatee Academy on Thursday following a bomb threat found no device, according to school system officials.

The middle school in northwest Hall County was evacuated about 12:45 p.m. Thursday after a student reported seeing a bomb threat on a bathroom stall, according to a press release from the Hall County School District.

The school district is offering a $1,000 reward for information leading to the identification of those responsible for the threat.  

Students and staff moved back into the building to resume normal activities. Afternoon dismissal was on schedule.

Parents were alerted by email, text message and phone about an hour after the initial report.

District spokesman Gordon Higgins said notification typically takes a half hour to hour as staff focus first on the safety of the students and officials, then work to ensure they release accurate information to parents.

Administrators at the school coordinate with those in the district office to get the messages sent as soon as officials are sure “the facts are straight” and all pertinent information is included, Higgins said.
