Which police code indicates that a subject is in custody and en route to the station?

The code that indicates a subject is in custody and en route to the station is 10-15. This specific code is widely recognized in law enforcement communications and is used to inform others that an arrest has been made and the individual is being transported for processing. Understanding the use of this code is essential for clear and effective communication among officers, as it ensures that all personnel involved are aware of the situation and can provide the necessary support if needed during the transport of the detainee.

The other codes relate to different situations; 10-16 typically refers to a situation involving a mental subject, 10-17 denotes a person in need of assistance, and 10-20 is used to ask for or provide a location. Each code serves its distinct purpose within police communications, highlighting the importance of using the correct terminology for efficient operations.
