If a defendant is arrested in a county without a bail set, how soon must the arresting officer notify the requesting law enforcement agency?

The correct answer is that the arresting officer must notify the requesting law enforcement agency immediately if a defendant is arrested in a county where no bail has been set. This immediate notification is crucial because it allows the appropriate authorities to take timely action regarding the situation of the defendant.

In the context of California law, ensuring prompt communication between law enforcement agencies is vital for maintaining the efficiency of the criminal justice process. This prompt notification helps in coordinating further actions, such as seeking the setting of bail or handling the case accordingly, ensuring the rights of the defendant are adhered to, and allowing for proper oversight of the process.

Other options suggest longer time frames that do not align with the legal requirements for immediate notification, highlighting the urgency of communication in such scenarios.
