Cal. PEN § 1299.08

(a) Except under exigent circumstances, an individual authorized by Section 1299.02 to apprehend a bail fugitive shall, prior to and no more than six hours before attempting to apprehend the bail fugitive, notify the local police department or sheriff’s department of the intent to apprehend a bail fugitive in that jurisdiction by doing all of the following:

(1) Indicating the name of an individual authorized by Section 1299.02 to apprehend a bail fugitive entering the jurisdiction.

(2) Stating the approximate time an individual authorized by Section 1299.02 to apprehend a bail fugitive will be entering the jurisdiction and the approximate length of the stay.

(3) Stating the name and approximate location of the bail fugitive.

(b) If an exigent circumstance does arise and prior notification is not given as provided in subdivision (a), an individual authorized by Section 1299.02 to apprehend a bail fugitive shall notify the local police department or sheriff’s department immediately after the apprehension, and upon request of the local jurisdiction, shall submit a detailed explanation of those exigent circumstances within three working days after the apprehension is made.

(c) This section shall not preclude an individual authorized by Section 1299.02 to apprehend a bail fugitive from making or attempting to make a lawful arrest of a bail fugitive on bond pursuant to Section 1300 or 1301. The fact that a bench warrant is not located or entered into a warrant depository or system shall not affect a lawful arrest of the bail fugitive.

(d) For the purposes of this section, notice may be provided to a local law enforcement agency by telephone prior to the arrest or, after the arrest has taken place, if exigent circumstances exist. In that case the name or operator number of the employee receiving the notice information shall be obtained and retained by the bail, depositor of bail, or bail fugitive recovery person.
