COPPERAS COVE, Texas (FOX 44) – If you saw a bunch of police cars and emergency vehicles at Copperas Cove High School on Friday morning, you should not be alarmed.

The Copperas Cove Independent School District released a statement Thursday saying that in order to ensure the safety and security of students and staff, there would be a mock exercise at the school around 9 a.m. This was done in partnership with the City of Copperas Cove Fire Department and Copperas Cove Police Department.

Emergency vehicles were on campus and in the buildings – as well as school, police and fire personnel.
