The lockdowns at Simmons Elementary School and Hatboro Horsham High School went into effect at 7:40 a.m. Friday after the Hatboro Horsham School District received an alert through the Montgomery County Emergency Communication System.
According to Superintendent Curtis Griffin, the two schools were locked down in response to both the alert and police activity in the area.
Neither the district nor police would say what prompted the alert.
"It's important to note that there were no issues or incidents within the schools," Griffin said in a statement released Friday afternoon. "This brief lockdown was simply an effective response to the emergency alert that we received. The schools followed Safe Schools and Emergency procedures."
School district officials said parents were notified through the district's email blast communication system.
School buses arriving at Simmons Elementary were rerouted to Keith Valley Middle School, which was outside of the lockdown zone.
The lockdown at both schools was lifted 45 minutes later, at 8:25 a.m.
Griffin said the district's Safe Schools Team will review Friday morning's lockdowns with an eye to improving safety and communications procedures throughout the district.
