(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;
(c) Performing a reasonable search of the detained person and his belongings when it appears that the merchandise or money may otherwise be lost; and
