There could potentially be an even less honest explanation. Perhaps the complaint was entirely vexatious, perhaps the person who laid it is the same person who fabricated the documents and sent them to FC.
Yeah that's right. I think we'd need more information to do anything more than speculate at this point. Going further, I feel like fabricating a police report to some degree comes with a presumption of moral blameworthiness. That is, all else being equal, I would tend to draw the inference that the fabricator is up to no good.
