A. No charges may be made pursuant to this chapter unless the person apparently in charge of the unruly gathering has been informed of his or her potential liability under this chapter by a police officer at the premises during the first visit. If, after a good faith effort, no such responsible party can be found, the warning may be given to any person in attendance at the unruly gathering.

B. The police department shall develop a written warning document to provide information concerning this chapter and shall deliver a copy of such warning document to the person described herein during the first visit to the unruly gathering. (Ord. 447 § 1 (part), 1990)
