Whenever the Attorney General deems it advisable to keep secret the identity of any special agent or investigator, claims for compensation and expenses of the special agent or investigator may be presented by the Attorney General in the Attorney General’s own name with the statement that the charges have been incurred under this article. When so presented the claims shall be paid out of any fund in the State Treasury allocated for the use of the Attorney General. Such claims are exempt from Section 925.6.
