Welf. & Inst. Code, § 652.5

(a) Whenever an officer refers or delivers a minor pursuant to subdivision (b) of Section 626, the agency to which the minor is referred or delivered shall immediately make such investigation as that agency deems necessary to determine what disposition of the minor that agency shall make and shall initiate a service program for the minor when appropriate.

(b) The service program for any minor referred or delivered to the agency for any act described in Section 602 shall include constructive assignments that will help the minor learn to be responsible for his or her actions.

The referral agency shall retain a copy of that written notification for 30 days.
