A mysterious phone call triggered a full emergency lockdown at Sparkman High School in Madison County, Alabama, on Tuesday, sending police officers to the campus as students and staff sheltered inside classrooms.
Following the call, teachers locked classroom doors, turned off lights, and kept students inside while law enforcement officers responded to the reported threat.
Police secured the school building and searched the hallways as officials worked to determine the nature of the threat and identify the person behind the call.
Authorities have not publicly identified the caller. Officials also have not disclosed what was said during the call or how the threat was communicated.
The incident created significant concern among families, with school officials urging parents to stay away from the campus while emergency operations were underway. Officials said keeping the area clear would allow law enforcement to respond without disruption.
Despite the tension surrounding the lockdown, school leaders confirmed early in the response that no one had been injured.
The investigation into the anonymous call remains ongoing as authorities work to establish who made the report and determine whether the threat was credible.
