A juvenile taken into custody at a state, municipal, or college police department for an offense that would not be classified as criminal if committed by an adult, or non-offender juveniles, such as dependent or neglected children, shall be held for identification, investigation, and processing purposes only in an unlocked, multi-purpose room that is not designated for residential use or secure detention. The child shall not be handcuffed to a stationary object and must remain in continuous visual supervision of an agency representative.
