"Missouri theme park enforces new rule following massive teen brawl"

Worlds of Fun amusement park in Missouri has implemented a chaperone policy after a fight involving 100 to 150 teenagers broke out over the weekend, requiring all people ages 15 or younger to be with a person who is at least 21 in order to "be admitted to, or remain in, the park after 4:00 p.m." The fight mostly involved teenagers, and an off-duty deputy was punched in the face by a teenage girl who refused to leave the park. This is not the first time a large fight has broken out at the amusement park.
