Hundreds of students, parents and supporters lined the street in front of Norman High School on Monday to protest the school’s handling of the bullying of three female students who allege they were raped by a former male student.

The protest was held in response to allegations from a 16-year-old who said she was raped Sept. 19 and bullied when she tried to return to school. After the girl made her accusations public, two other girls said they were raped by the same student.

Norman police said they are investigating the case, and Cleveland County District Attorney Greg Mashburn said his office is waiting until police complete their investigation.

“We want to make sure we file the right charge on the right person,” Mashburn said, adding that such a decision likely would not arrive soon.
