The victim was a mere two blocks from school when she says she was abducted at knifepoint, taken to another location, and sexually assaulted at gunpoint.
She told police the suspect then drove her back to school and dropped her off after the assault.
The victim ran to her school and told administrators what had happened. Authorities said they need the public's help because there were no witnesses.
The girl gave police a suspect description: male African-American in his early 20s, tall, thin, with braided hair. The vehicle was described as a larger four-door black sedan with tinted windows.
School officials sent a letter to parents describing the incident, and police patrolled the area around the school.
"It's alarming that this would happen in the neighborhood, and I'm surprised that he actually picked someone of that age, you know, as opposed to some of the younger kids because I see them walking a lot by themselves too," said parent Andre Peterson.
Anyone with information is urged to call the Hawthorne Police Department at (310) 349-2700.
