Police in Rotterdam, the Netherlands, arrested an 18-year-old for calling on social media for violence against her school and a teacher who refused to remove for some controversial caricatures from the classroom.
A teacher at Emmaus College in Rotterdam has withdrawn from the public eye due to threats.
The caricature shows a beheaded man clenching his tongue against the jihadist who beheaded him. The man is wearing a T-shirt of the French satirical weekly Charlie Hebdo, which has repeatedly published caricatures of the Prophet Muhammad in the past, angering Muslims.
After the recent beheading of a French teacher who showed a caricature of Charlie Hebdo during a lecture on freedom of speech, students at Rotterdam High School asked their teacher to remove the caricature, saying it was offensive, but he refused to do so.
The photo of the caricature then circulated on social media, prompting threats against the teacher, reports the German news agency dpa.
