DELRAY BEACH, Fla. - Students at Atlantic High School have been allowed back inside the building after an earlier evacuation due to a bomb threat, according to the the Delray Beach police.
FCAT testing has been canceled at the school for Monday.
Police say someone called the local police department with the threat.
Detectives say it's unusual for a bomb threat to be called into the police department, when the threat was made against the school.
"We don't get bomb threats every day, so to get a bomb threat in general is pretty unusual. For us to get it, you can't say anything is unusual nowadays,” said Delray Beach police Sgt. Nicole Guerriero.
Students were taken to the stadium's bleachers while officials searched the school.
Just after 11 a.m., officials tweeted that all is clear following their investigation and students are safe.
Police say they are actively working to find and arrest the person responsible for the threat. Administrators are working out a new testing schedule for students.
