When 13-year-old Linus refused to take off his mask at school, he was locked in a room. There he had to wait until his mother came and picked him up.
When the school reopened after the sports holiday, Linus wanted to wear a mask. Several of the school staff had previously been infected with Covid-19 and therefore the school had had distance education for two weeks before the sports holiday.
But the staff at school would not allow Linus to wear a mask. When he would not take it off, the school called his mother, who had to take him home.
