Dee Barnes was a rapper who hosted a TV show about rap. She probably read periodicals on the subject as well. After interviewing former N.W.A member, Ice Cube, in 1990, the rest of N.W.A decided that they were going to kick the s**t out of her because they have a strict "interview Ice Cube and get the s**t kicked out of you" policy.
It's all in the N.W.A. Constitution.
When Dre found her at a record release party shortly after the interview, he "picked her up" and "began slamming her face and the right side of her body repeatedly against a wall near the stairway" as his bodyguard held off the crowd. After Dre tried and failed to throw her down the stairs, he began kicking her in the ribs before chasing her into the women's bathroom and donkey punching her a few times for good measure.
