False Allegations Property Invasion, Damages, Trespass

I have been accused of looking at my step daughters breast and that i was slapping her on the butt. She started saying this after i confronted her about wearing a shirt that was too revealing. now she has her boyfriend telling people he has seen me do this as well. I simply told her to put a bra on or put on another shirt. She is seventeen and is some what out of control. She is on probation and i just filed a vandalism report with the local pd for her vandalizing my truck.She also went to the local pd to report her allegations. Should i be worried or should i just let it go. I have a very high profile job and just the allegation alone could cost me my job what should i do to protect myself. I live in oklahoma

 

I failed to mention that this is not the first time she has made accusation just to later admit to her probation officer she lied to get her way. She is not very credible but the accusation is such that it makes you look like a perv when you really are'nt. What should i do now?
