The city council may suspend, revoke, withdraw or discontinue any license granted under the provisions of this title whenever the council has reason to believe that the business conducted thereunder by the licensee, his servants or employees, is a nuisance, a menace to public health or detrimental to the peace and morals of the city, or that violations of the laws of the state or of the ordinances of the city have been committed or are being permitted to be committed upon the premises where such business is being conducted. Such suspension, revocation, withdrawal or discontinuance shall be by resolution duly made and carried and spread upon the minutes of the council. (Prior code § 13-17)
