What is the meaning of "61" or "10-61" in police radio 10 codes?

In police radio communications, the code "10-61" specifically refers to "suspect in custody." This code is a part of the "ten-codes" or "ten signals," which are brevity codes used by law enforcement personnel to communicate succinctly over radios. The use of such codes helps to reduce confusion over the airwaves and ensures that officers can relay information quickly and efficiently during high-pressure situations.

Understanding this code is crucial for effective communication among officers, especially in scenarios where immediate clarity is required regarding the status of suspects. When an officer indicates that there is a "10-61," it signals to others that a suspect has been apprehended and can impact how other officers and units respond to the incident. This code helps to allocate resources appropriately and ensures that necessary protocols for handling apprehended suspects are followed, maintaining the safety of officers and the public.

Other choices do not align with this specific coding system. For instance, "suspicious person" and "active shooter" are not represented by the code "10-61," highlighting the importance of knowing the exact meanings of ten codes in active response situations.
