According to police and witnesses quoted in the Courant, the violence mushroomed among a crowd that had gathered among tailgaters without tickets to the sold-out show. As members of the crowd grew increasingly inebriated with a mixture of alcohol and nitrous oxide, bonfires fueled by abandoned furniture other debris were lit. The crowd then overturned two cars (later setting them aflame) and began a rampage of vandalism on other vehicles in the area. A similar scene materialized the following night.
In all, more then 50 people were arrested and dozens were reportedly injured. Most injuries reportedly came from broken beer bottles thrown during the melee or by falling on the shattered glass that covered parts of the parking lot. Others suffered minor injuries after getting hit by rubber bullets and beanbag rounds fired into the crowd by police.
As a result of the problems, the venue has a adopted a new rule that restricts parking in the lots surrounding the amphitheater to ticket-holders.
