Any merchant, his agent or employee, who has reasonable grounds

mercantile establishment, may detain such person in a reasonable

manner for a reasonable length of time for all or any of the

following purposes:

(a) Conducting an investigation, including reasonable

interrogation of the detained person, as to whether there has been a

wrongful taking of such merchandise or money;

(b) Informing the police or other law enforcement officials of

the facts relevant to such detention;

his belongings when it appears that the merchandise or money may

otherwise be lost; and

taken wrongfully. Any such reasonable detention shall not

constitute an unlawful arrest or detention, nor shall it render the

merchant, his agent or employee criminally or civilly liable to the

person so detained.
