Two 11-year-olds in Viersen on the Lower Rhine wrote in a note at their school announcing an explosion at the nearby playground, triggering a police operation. Only then did it become clear that the chemistry lessons had inspired the students, police said. The investigators confirmed that they did not want to blow up the school or take her out of the school. Instead, they wanted to replicate the experience they had already tried in class and show it to other children on the playground.
However, their announcement was momentous: Police took seriously the letter found at the high school on Tuesday, promising a bombing the same afternoon, the statement said. The school was evacuated, with only a few students remaining. The playground is closed. An explosive dog searched for a possible explosive device.
