(a) He or she has reasonable cause to believe that the defendant is in a particular county other than the one in which the warrant is returnable; and

(b) The geographical area of employment of the delegated police officer embraces the locality where the arrest is to be made. 5. Under circumstances specified in subdivision four, the police officer to whom the bench warrant is addressed may inform the delegated officer, by telecommunication, mail or any other means, of the issuance of the warrant, of the offense charged in the underlying accusatory instrument and of all other pertinent details, and may request him or her to act as his or her agent in arresting the defendant pursuant to such bench warrant. Upon such request, the delegated police officer is to the same extent as the delegating officer, authorized to make such arrest pursuant to the bench warrant within the geographical area of such delegated officer's employment. Upon so arresting the defendant, he or she must without unnecessary delay deliver the defendant or cause him or her to be delivered to the custody of the police officer by whom he or she was so delegated, and the latter must then without unnecessary delay bring the defendant before the court in which such bench warrant is returnable. 6. A bench warrant may be executed by an officer of the state department of corrections and community supervision or a probation officer when the person named within the warrant is under the supervision of the department of corrections and community supervision or a department of probation and the probation officer is authorized by his or her probation director, as the case may be. The warrant must be executed upon the same conditions and in the same manner as is otherwise provided for execution by a police officer.
