If the initial appearance does not occur within 24 hours after arrest, the arrested person must be immediately released from custody. If a misdemeanor warrant states the amount of a deposit, cash, unsecured, or secured appearance bond as provided in Rule 3.2(a)(3), and the arrested person has posted the bond prior to the initial appearance, the arrested person must be promptly released from custody.(b)On Arrest Without a Warrant. A person arrested without a warrant must be taken before the nearest or most accessible magistrate either in the county of arrest or in the county where the offense was committed.

If a person is arrested in a county other than the one where the warrant was issued, the person must be taken before the nearest or most accessible magistrate in the county of arrest or in the county where the offense was committed. If eligible for release as a matter of right, the person must then be released under Rule 7.2.
