A 13-year-old French student has admitted to spreading lies about her 47-year-old history teacher, Samuel Paty, before he was beheaded by an Islamic extremist last year. Business Insider reports that Paty allegedly showed students controversial photos of the Prophet Muhammad during a civics class about free speech. The girl’s father launched an online campaign against the teacher based on his daughter’s account, which police had said at the time was linked to 18-year-old Abdullakh Anzorov’s attack on the teacher. Now the girl has walked back her claims, confessing to police that she lied about being in class that day and falsely accused Paty of asking Muslim children to leave while he showed the photos. The girl has been charged with slander, and her father and another man behind the hate campaign have been charged with “complicity in murder”.
