On Tuesday morning it was announced that the VMBO Pascal South had closed its doors after the school had received a threatening email. Photos of firearms were attached to the email. According to a spokesperson for the school, the message stated that the sender wanted to harm the students and teachers.
All suspects come from Zaandam. The two boys arrested on Saturday are in restrictions, meaning they are only allowed to communicate with their lawyer. The boy who was arrested on Tuesday has since been released, but his involvement in the case is being further investigated, the police said.
