(a) The division may enforce the provisions of this code and all labor laws of the state the enforcement of which is not specifically vested in any other officer, board or commission. Except as provided in subdivision (d), in the enforcement of such provisions and laws, the director, deputy director, and such officers and employees as the director may designate, shall only have the authority, as public officers, to arrest without a warrant, any person who, in his presence, has violated or as to whom there is probable cause to believe has violated any of such provisions and laws. In any case in which an arrest authorized by this subdivision is made for an offense declared to be a misdemeanor, and the person arrested does not demand to be taken before a magistrate, the arresting officer may, instead of taking such person before a magistrate, follow the procedure prescribed by Chapter 5C (commencing with Section 853.6) of Title 3 of Part 2 of the Penal Code. The provisions of such chapter shall thereafter apply with reference to any proceeding based upon the issuance of a citation pursuant to this authority.
