Police say the children, ages 10 and 11, attend Clifton Elementary School 11. All five have been suspended.

According to ABC 7, police learned that the children were planning to deploy an explosive device during an assembly that was set to take place at the high school Wednesday night.

"Teachers and administrators at Clifton Elementary School # 11 uncovered written plans on how the attack would occur and contacted police," the story states.

During the course of an investigation, police were able to locate the device, although no actual explosives were found inside.

A story by NJ Advance Media indicates that police also said someone else may have helped the students devise the plan.

The students were taken into custody and later released to their parents. Police have not yet filed charges against any of the children.
