If the executive authority of a state demands of the executive authority of this state a fugitive under AS 47.30.410 and produces a copy of the commitment decree or other judicial process and proceedings, certified as authentic by the governor or chief magistrate of the state from which the person so charged has fled, with an affidavit made before a proper officer showing the person to be a fugitive, the executive authority of this state shall have the fugitive apprehended and secured, if found in this state, and have immediate notice of the apprehension given to the executive authority making the demand, or to the agent of that authority appointed to receive the fugitive, and have the fugitive delivered to the agent when the agent appears. If no agent appears within 30 days from the time of the apprehension the fugitive may be discharged. All costs and expenses incurred in the apprehending, securing, maintaining, and transmitting the fugitive to the state making the demand shall be paid by that state. An agent so appointed who receives the fugitive into custody is empowered to transmit the fugitive to the state from which the fugitive fled. The executive authority of this state may, on the application of a person interested, demand the return to this state of a fugitive under AS 47.30.410 - 47.30.460.
