The person shall not be released within the seventy-two hours until after the person has been examined and evaluated by the designated mental health professional unless the court in its discretion releases the person sooner after a determination regarding probable cause or on probation bond or bail.
Within twenty-four hours of the arrest, the arresting law enforcement agency shall refer the person to the designated mental health professional for examination and evaluation under chapter 71.05 or 71.34 RCW and inform a parent or guardian of the person of the arrest, detention, and examination.
