Are you sure it was a report or was it just a call? You have absolute privilege in reporting crimes which means even if it's done in malice/falsely, they can't be held liable for it. However, if they continued to prosecute for malicious purposes and without reasonable cause, etc... it could be malicious prosecution in your state. If they were using the system just to harass you and you can PROVE that by a preponderance of the evidence, you could sue for abuse of process.
However, it sounds like it's just something you should let go.
