A.R.S. § 13-3854: Arrest without a warrant

The arrest of a person may be lawfully made also by any peace officer or a private citizen without a warrant upon reasonable information that the accused stands charged in the courts of another state with a crime punishable by death or imprisonment for a term exceeding one year, but when so arrested the accused must be taken before a judge or magistrate with all practicable speed and complaint must be made against him under oath setting forth the ground for the arrest as in section 13-3853, and thereafter his answer shall be heard as if he had been arrested on a warrant.
