Three schools on the North Allegheny School District's Cumberland campus were on lockdown this morning.
A phone alert to parents of students at McKnight Elementary, Carson Middle and North Allegheny Intermediate High schools said some kind suspicious activity outside the high school prompted the lockdown without being more specific.
The district's communications director, Joy Ed, wrote in an email that a student's report of a suspicious person prompted the lockdown about 10:15 a.m.
"All students and faculty are safe inside buildings at this time," she wrote. "The police are on the Cumberland Campus investigating this report. As more information becomes available, the District will communicate with parents via the website and School Messenger."
A message broadcast over the campus intercom at 11:15 a.m. said the schools should return to "normal operating procedures."
McCandless police are leading the investigation and would not release any information at the scene.
According to a second district statement, "A large contingency of police officers responded to investigate this report. The Cumberland Campus and the immediate area surrounding the campus was searched. The police found the area to be clear and safe. At NAI, the class schedule will be modified for the remainder of the day. All students will have a lunch period. At McK and CMS, class schedules were not disrupted."
