Cal. Penal Code § 279.5

When a person is arrested for an alleged violation of Section 278 or 278.5, the court, in setting bail, shall take into consideration whether the child has been returned to the lawful custodian, and if not, shall consider whether there is an increased risk that the child may not be returned, or the defendant may flee the jurisdiction, or, by flight or concealment, evade the authority of the court.
