The character "Sly" is credited as being a lieutenant. When he is talking to Mahoney at the station, he opens a door that says "Lt. S. Sullivan" and goes in and sits at the desk, indicating this is his office. His uniform jacket and shirt have three stripes on the right sleeve, indicating his rank is that of sergeant.
