One of the kids in class (13 year old) complained to her parents after having had that class where the teacher discussed freedom of the press. He showed a Mohammed cartoon.

The father then uploaded a vid on social media telling people the teacher shoud be stopped by any means.

The 18 year old Chechen answered the call, so to speak. He lived approximately 100 kilometres away from the school. He had no ties to the school, the teacher or the parents.

The teacher had told the kids in advance that his next class was going to be sensitive to Muslim kids and he had told them they could opt out of that particular lesson.

By all accounts the teacher was well liked at school.
