This sounds like a problem and case, but needs more discussion. The police must assume reports are true, but have resources available before they act... especially with such force. However, the question is were the officer's acts reasonable under the circumstances, what is in their background and detailed analysis of what happened. These cases are very difficult and fact intensive. Call a local personal injury or civil rights lawyer.

you need an attorney willing to immediately apprise the state that law enforcement arrested the wrong person and their 'alleged' victim made a false police report, punishable by law. in fact, the state needs to immediately know before they subpoena the alleged victim and law enforcement from the incident. it's only after the 'invest' that the prosecutor decides whether or not to file formal charges (an 'information'). best to nip these situations in the bud.
It will be incredibly difficult to convince the court that there was an outright lie about an incident, but it there is an actual mistake then it can be remedied by a criminal defense attorney.
