The Burlington Police Department received a call at approximately 9:30 a.m. that said there was an active shooter inside Walter M. Williams High School in Burlington, according to public information officer Emily-Lynn Adkins.
A Dec. 1 press release said once on campus, responding officers — in tandem with two on-duty school resource officers, who were already on site — determined that there was no evidence that supported an active threat to the campus, students and staff.
A tweet from the Alamance-Burlington School System at 10:39 a.m. said the department placed the school on lockdown.
The 911 call was deemed a false report and a 10:57 a.m. tweet announced the lift of the lockdown.
The investigation is ongoing and the press release said detectives are still working to gather information regarding the false call.
