A written threat in a boys restroom led to a 50-minute lockdown at Edgewood High School on Friday that lasted until police determined it was safe to resume classes.
The threat was investigated by Butler County Sheriff’s deputies, said Edgewood Schools spokesperson Pam Pratt.
“They (deputies) did a clean sweep of the facility and nothing was found to be credible,” Pratt said.
The lockdown, which required students and teachers to stay in their classrooms, lasted from 11:30 a.m. to 12:19 p.m. in the St. Clair Twp. school that enrolls 1,200 students in grades 9-12.
School officials and police are continuing their investigation.
