GRANITE CITY — School district officials placed Coolidge Junior High School on lockdown Thursday after a mental health agency notified police of a threat to the school.
According to a letter to parents from Superintendent Jim Greenwald, police and school resource officers locked down the school after the threat was received at 3:24 p.m., and students were confined to classrooms. Students on buses were brought inside; buses arriving after the lockdown were directed to off-site parking.
Because Granite City High School is next door to the junior high, a lockdown was also put in place for the students on the high school campus for after-school activities.
After consulting with police, school officials ended the lockdown and dismissal resumed at about 4 p.m. Police took a suspect into custody and officials determined the suspect had not been on or near school property during the incident.
The school district used the automated call system and website to notify parents about the situation. According to the letter, the district is working with police to review the lockdown.
