A 24-year-old Lincoln woman attacked in April in a road rage incident is suing her alleged attackers.

Court records show that Heather Nelson filed the lawsuit in Lancaster County District Court earlier this month against four other women. They are Patricia Johnson, Jeralyn Whitfield, Christina Campbell and Quanetta Campbell, who all face criminal charges in the case.

Police say the attack happened in the early hours of April 6 after Nelson's car was involved in a fender-bender with another car.

Police say Nelson got out of her car, but became frightened when women in two cars began threatening her. She drove to a friend's house, and police say it was there she was attacked by the group.

Nelson's lawsuit says her medical expenses following surgery have exceeded $20,000.
