Forest Park High School was on extra alert Monday after a security threat was reported.
This threat also affects North Western High School since they are currently in the same building as Forest Park.
Officers say they are still scanning the building, and students and teachers are still inside.
The school released the following statement:
Over the weekend, City Schools worked with all appropriate agencies to investigate a threat to Forest Park High School. It was not a bomb threat. This morning, in an abundance of caution, students went through extra security when entering the building and were kept in the cafeteria, while school and city police completed their search of the entire building. The building was found to be safe and secure, and students and staff returned to their regular schedule. City Schools takes all matters of security seriously. Additional school police will be on site at the school throughout this week to ensure the safety of all students and staff.
