Johnson Elementary School was briefly evacuated Tuesday morning after a threat was made, a Limestone County Schools spokeswoman said.
District spokeswoman Karen Tucker said a phone call was made to the school around 7:15 a.m. and students were evacuated as a precaution.
Limestone County Sheriff's Office deputies searched and cleared the building, and students were being taken back into the building around 8:15 a.m., Tucker said.
Parents were lining up at the school to pick up their children. Tucker said parents could choose to take their children home or leave them at school, and that absences for the day would be excused.
