Police in Japan say a teacher stabbed to death a 12-year-old girl Saturday in the country's third killing of a school girl in less than three weeks.
Yu Hagino, 23, was arrested at the murder scene, a school in the western city of Uji.
Police say the suspect confessed to stabbing the girl with a knife after arguing with her.
The killing follows the recent murders of two school girls in the space of just over a week. The two were killed in separate incidents as they walked home alone from elementary school along deserted roads.
