(a)    Before taking any enforcement action under this chapter, a police officer shall ask the apparent offender’s age and reason for being in the public place.  The officer shall not detain the minor, issue a citation or make an arrest under this chapter unless the officer reasonably believes that an offense has occurred and that, based on any response and other circumstances, including any investigation that a reasonable person would deem necessary, none of the exceptions enumerated in this section apply.
   (b)    Upon determining that enforcement action is warranted under this chapter, a police officer may arrest and detain any minor violating this chapter until the parent, guardian or custodian is notified. The minor may be released upon the giving of a promise by the minor and his or her parent or guardian or custodian that the minor together with his or her parent, guardian or custodian will appear at a stated time before the proper authority to answer to the charges.
