Male Student, 15, Held in Teacher's Stabbing Death

Police arrested a 15-year-old student today at a Catholic school in Leeds, England, after he allegedly stabbed a teacher there. The teacher, whom students identified as Anne Maguire, 61, was taken to the hospital, but later pronounced dead, the Telegraph reports. "We would like to reassure people that this has been an isolated incident and there is no ongoing risk to pupils or staff," a police official said. "The situation is under control," he added, and "the rest of the school is continuing to operate as normal."

Corpus Christi Catholic College has almost 1,000 students. Maguire reportedly taught Spanish and Religious Education there, and there were no shortage of students mourning her on social media. "Absolutely disgusting and sickening to think someone could act in that way to such a lovely, funny and caring lady!" one student wrote. Another former student, 18, called her "the best teacher in the world," adding, "She cared about everyone even after they left school. It's absolutely devastating to hear that she's gone."
