A merchant or merchant's adult employee who
has probable cause for believing that a person has violated this chapter
in his presence may detain such person in a reasonable manner for
a reasonable length of time to deliver him to a peace officer or to
his 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 shall not be interrogated or searched against his will before
the arrival of a police officer who may conduct a lawful interrogation
of the accused person. Compliance with this section entitles the merchant
or his employee effecting the detention to the same defense in any
action as is available to a peace officer making an arrest in the
line of duty.
If the value of the merchandise does not exceed
$100, any person violating this chapter shall forfeit not more than
$200. If the value of the merchandise exceeds $100, this chapter shall
not apply and the matter shall be referred to the County District
Attorney for criminal prosecution.
