Minors held in temporary custody at a Sheriff's Station/Unit shall not be securely detained unless they meet the following criteria:
The minor is 14 years of age or older;
There are facts or circumstances present that would lead a prudent peace officer to conclude that further criminal activity against persons or self-destructive acts on the part of the minor are likely, or that the minor may be at risk of harm if released; and
A brief time (no more than six hours) is required to investigate the case, facilitate release of the minor to a parent, guardian, or responsible relative, or arrange for the transfer of the minor to an appropriate juvenile facility.
