If an officer authorized to make arrests in the state, a licensed physician, a psychologist authorized under §33-6-427(a), or a professional designated by the commissioner under §33-6-427(b) has reason to believe that a person is subject to detention under §33-6-401, then the officer, physician, psychologist, or designated professional may take the person into custody without a civil order or warrant for immediate examination under §33-6-404 for certification of need for care and treatment.
