The Commission for the Promotion of Virtue and Prevention of Vice in Madinah intervened Wednesday morning to break up a gathering of a group of joyriders who were performing various stunts and harassing students of Girls' Middle School No. 46. The trouble started when nearly 400 girls showed up at the school to pickup the results of their final exams. School administrators, however, had not yet finished printing them and asked the girls to wait outside until all of the results had been printed and placed in order. Young men immediately began taking notice of the large gathering of girls and nearly a dozen cars began playing loud music, drifting and performing a popular stunt known as a donut, in which drivers perform 360-degree spins that make the car's tires screech. Commission members were called to the scene and they used loudspeakers to urge the men to go home. They also convinced the school's principal to let the girls wait inside. Ahmad Al-Hari, a parent, told Okaz that three cars belonging to the commission were parked outside of the school throughout the afternoon until most of the girls had safely left the building. Call to the commission's official spokesman in Madinah, Sultan Mutairi, went unanswered. __
