The chief of police may revoke or suspend the license of any person issued under the
provisions of this article if the applicant has knowingly made any false, misleading
or fraudulent statement of fact in the licensing application; or upon any grounds
that would warrant the denial of issuance of the license in the first place; or for
permitting gambling within the billiard hall. Notice of the suspension or revocation
shall be given to the licensee in writing, with the reasons for the suspension or
revocation specified in the notice. The notice shall be served either by personal
service upon the licensee, or by posting the notice upon the establishment.
