Absolutely it is harmful to your career and as such could be defamation of character.
If no reports were made when it supposedly happened, I suggest she has to have a first hand witness or a confession. So I suggest that you will not want to talk to her, lest she has an investigation
pending and try to get you to admit to this.
In the meantime, I suggest that you contact a local defamation attorney and have them write her a cease and desist letter stating that this is a serious matter of defamation and if she continues you will sue her for the same.
Remember, the state has to prove beyond a reasonable doubt your guilt and if there are no first hand witnesses, DNA, or a confession they will not be able to do that.
