Sec. 11-3-6 Retail Theft.
   (a)   Whoever intentionally alters indicia of price or value of merchandise or takes and carries away, transfers, conceals or retains possession of merchandise held for resale by a merchant without consent and with intent to deprive the merchant permanently of possession or the full purchase price may be penalized as provided in Subsection (d).
   (b)   The intentional concealment of unpurchased merchandise in a merchant's store is evidence of intent to deprive the merchant permanently of possession of such merchandise without paying the purchase price thereof. The discovery of unpurchased merchandise concealed upon the person or among the belongings of another is evidence of intentional concealment on the part of the person so concealing such goods.
   (c)   A merchant or merchant's adult employee who has probable cause for believing that a person has violated this Section in his/her presence may detain such person in a reasonable manner for a reasonable length of time to deliver him/her to a law enforcement officer, or to his/her parent or guardian if a minor. The detained person must be promptly informed of the purpose for the detention and may make phone calls, but he/she shall not be interrogated or searched against his/her will before the arrival of a law enforcement officer who may conduct a lawful interrogation of the accused person. Compliance with this Subsection entitles the merchant or his/her employee affecting the detention to the same defense in any action as is available to a law enforcement officer making an arrest in the line of duty.
   (d)   If the value of the merchandise does not exceed One Hundred Dollars ($100.00), any person violating this Section shall forfeit not more than One Thousand Dollars ($1,000.00). If the value of the merchandise exceeds One Hundred Dollars ($100.00), this Section shall not apply and the matter shall be referred to the District Attorney for criminal prosecution.
