Any person who shall remove, store or keep any such vehicle at the request of the police department or any officer thereof shall have a lien on such vehicle for the reasonable value of such services. Such lien shall be superior and prior to any mortgage or title retaining contract on such vehicle, and if such charges are not paid within thirty (30) days after mailing of the notice required by this chapter, or after thirty (30) days from the date of removal if no notice is required hereof, the person performing said services may proceed to sell said vehicle at public auction by giving ten (10) days' public notice of the sale by advertising in the official newspaper of the city, which notice shall contain a description of the property to be sold, the time and place of sale and the terms and conditions of the sale. The proceeds of the sale must be applied to the discharge of the lien and costs, and the remainder, if any, must be paid over to the owner of the vehicle. (Ord. 29, 8-19-1970)
