It is unlawful for any pawnbroker or dealer, his or her clerk or employee, to receive in pledge or purchase, or on consignment, any article or thing from any person under 18 years of age, or from any person who is at the time intoxicated or from any habitual drunkard, or from any person known to the pawnbroker or dealer to be addicted to the use of narcotic drugs, or from any person who is known to be a thief or a receiver of stolen property, or from any person who he has reason to suspect or believe to be such. The fact of lending money upon or purchasing goods from any of the classes of persons enumerated in this section shall be prima facie evidence of an intent on the part of such pawnbroker or dealer, his or her agent or employee, to violate this chapter. (Ord. 4891 § 12, 1996; Ord. 2891 § 6, 1981; 1961 code § 5.37.100.)
