Usually a person who has had their fingerprints and mug shot taken are considered under arrest and booked for violation of a criminal law. Even if the arrest does not result in a actual warrant being filed, or a criminal conviction for the offense, you will still have an arrest record. You should first check with your local district or juvenile court to see if a warrant ever issued without you knowing it. If so, then you must address it in criminal court. If not, then you must have your arrest record destroyed per the rules and regulations of your state law.
