Two Killeen ISD elementary school campuses were locked down Friday, while police responded to a nearby disturbance.

A district spokesperson said school administrators initiated an external lockdown at Harker Heights Elementary School at 11:50 a.m. The lockdown ended at 12:25 p.m., after police gave the all-clear.

Separately, East Ward Elementary School was put on an external lockdown for a similar situation. The lockdown began at 1:50 p.m. and ended shortly thereafter at 2:05 p.m.

The district said students and staff were never in any danger and parents were notified about both incidents.

"The safety of students and staff will remain a top priority of the district," Killeen ISD said in a statement.

A spokesperson for Killeen Police said the cause of the East Ward Elementary School lockdown was police were dispatched to a report of shots fired in the 1300 block of Harris Avenue in Killeen. When officers responded, they advised the school to enter a lockdown. However, police were unable to locate a shooter and gave the all-clear after searching the area.

The cause of the Harker Heights Elementary School lockdown was not immediately clear.
