Corrected entry: In this book Percy takes 10 points from Gryffindor, when Ron Harry and Hermione are outside the girls bathroom on the second floor. "Ten points from Gryffindor" said Percy, fingering his prefect badge. However, later in the series, once Umbridge begins teaching, Malfoy tries to dock points from Harry, Hermione and Ron, and Hermione says "Prefects can't take points from students, Malfoy, only teachers can".
