Police in Clifton, New Jersey, say five fifth-grade students were arrested after they allegedly planned to set off explosives at the local high school.
According to Clifton police, the students at School 11 were found with written plans for attacks at Clifton High School.
According to the Bergen Record, the students brought a fake explosive device on a field trip to the high school. The device contained vinegar and cinnamon and was determined to be nonfunctioning.
The children have been released into the custody of their parents, but are suspended from school, police said.
School district officials could not immediately be reached for comment Wednesday evening.
