KHARTOUM, Sudan (CNN) — A Sudanese court found a British teacher guilty of insulting religion and sentenced her to 15 days in prison Thursday for allowing a teddy bear to be named “Mohammed,” British authorities and her lawyer reported. Gibbons, 54, was arrested Sunday after she asked her class of 7-year-olds in Khartoum to name the stuffed animal as part of a school project, the British Foreign Office said. She had faced charges under Article 125 of Sudan’s constitution, the law relating to insulting religion and inciting hatred. Appearing somber and dazed, Gibbons arrived at the central courthouse in Khartoum for her closed hearing early Thursday. A staff member from the British Embassy in Khartoum and defense lawyers attended the hearing with her. The courthouse was heavily guarded by police, who kept journalists — and, for a while, even one of her attorneys — away. MORE
