Police said one child was taken into custody, and there were no reports of any injuries.

No weapons were involved, police said.

The lockdown was quickly lifted, but students and staff followed safety protocols by moving to a position of safety, which included some evacuating the building, school officials said in a letter to families.

Naperville police and a school resource officer handled the incident, and there was no broader threat to the school.

Classes wrapped up for the day, as scheduled.

"We take all safety-related matters very seriously and use incidents like this as opportunities to reinforce the importance of maintaining a safe and secure school environment. This level of our alert system should be reserved for the highest level of safety risk and, as we do each time, we will engage in a comprehensive review of this incident, our procedures, and any necessary training," the letter said.
