A bomb threat was discovered Thursday evening on a locker room wall at Pine-Richland Middle School, according to school officials.
Northern Regional Police Department did a sweep of the building and found it to be clear, said the communications director for Pine-Richland School District, Rachel Hathhorn, in an e-mail sent to middle school parents and staff.
As a precaution, police were scheduled to make a second sweep.
"The police made a second sweep with dogs this morning (Friday) and gave the all-clear," Hathhorn said. No students or staff were permitted to enter the building until after 7 a.m.
Middle school parents and staff were notified by phone and email through the district's automated communication system.
Hathhorn emphasized that the district makes safety a top priority.
