Police in the US say more than 90 people were hospitalised during a Connecticut concert featuring superstar rapper Chance the Rapper.
Police said many were taken to hospitals for excessive drinking.
Hartford Deputy Chief Brian Foley said Saturday that officers made 50 underage drinking referrals Friday at Hot 93.7′s Hot Jam concert at Xfinity Theatre in Connecticut, reports news.com.au.
Most of those charged were issued a summons to appear in court. Several other arrests were made throughout the evening.
Police say the crowd was apparently made up of people in their late teens and early 20s. He says tailgating, partying and excessive alcohol consumption was "extremely prevalent."
