You can call the police station and ask them directly. However, if they aren't ready to "interview" you, they aren't likely to admit they have a complaint sworn out against you. If you didn't do anything illegal, then this guy is just trying to get under your skin and bully you. In any event, you aren't really likely to find out unless and until the police want to talk to you about the allegations. At that point, you really should decline to talk to them at all. That means that you should just politely tell them that you choose to remain silent and want to talk with an attorney. Even if you really haven't done anything wrong, the more you say the more the police are able to use against you in their own way. It just isn't a good idea to try to explain the situation.
If you are contacted, then you will want to call a criminal
defense attorney right away and sit down with them and discuss exactly what happened so that they can give you the best advice about your best course of action. That might include talking with the police, but only with an attorney present.
