About 12,000 fans turned out for a performance by the Rolling Stones on their first visit to Zurich, April 16. All of a sudden, "chaos." The tumult started when several frenzied fans tried to climb onto the stage. One of them fell, resulting in a skull fracture. Suddenly hundreds of fans "joined in" and started smashing stools and furniture, followed by various smoke bombs. During the performance and melee, 250 policemen and 150 security guards understandably were kept quite busy. Fifteen fans were arrested and ten were injured. Here, leader Mick Jagger leads the group.
