 Deputy police chief describes it as a "busy night" 
 
 (CNN) More than 90 people were hospitalized in Connecticut during a concert headlined by musician Chance the Rapper, authorities said. 
 
 Hartford Police officers made 50 underage drinking "referrals" at the event Friday night, Deputy Chief Brian Foley tweeted. 
 
 He described it as a "busy night, saying most patients were underage concertgoers who suffered severe alcohol intoxication. 
 
 "Additional steps will have to be taken to address these issues at these concerts," he said. 
 
 The three-time Grammy Award winner was part of the lineup during Hot 93.7's Hot Jam concert at Xfinity Theatre in Hartford.

 The number of people taken to the hospital on Friday night far exceeds what is typical for a concert in the city, Deputy Police Chief Brian Foley said. 
 
 "A 'typical' concert is around 20-30 transports. 60 would be very bad. We had 70 once and 90 last night," Foley said. "It depends on the act that is in town and the fan base age." 
 
 Hartford Fire Capt. Raul Ortiz said the "constant cycling of transports" overwhelmed the department. 
 
 Hartford's ambulance provider had to call in additional resources and some patients had to be taken to hospitals in Farmington, Manchester and New Britain, Ortiz said. 
 
 "When it's at this level, you're tapping into all your resources in the area," he said. 
 
 A large number of the patients were underage concertgoers experiencing "severe intoxication," Foley said. 
 
 While police officials said 90 people were taken to the hospital, Ortiz said his department's incident commander thought the number was even higher, estimating that more than 100 people were brought to hospitals. 
 
 Thirty alone were taken to Hartford Hospital. 
 
 Connecticut Children's Medical Center in Hartford saw at least 15 patients from the concert, mainly teenagers, including a 19-year-old male with a blood-alcohol content of nearly 0.5, said John Brancato, assistant director of the hospital's pediatric emergency department.

 That's eight times the legal limit for driving. The teen was so intoxicated he had to be restrained and nearly intubated — had a tube inserted to help with breathing — said Brancato, who was working Friday night. He eventually was admitted to the intensive care unit for close monitoring. 
 
 "It's just crazy," Brancato said. "It's not like adult social drinking, where you're out with friends or family and you have a glass of wine or beer, or two, or three. 
 
 "With the kids who get brought into the hospital, they drink with one sole purpose, and they don't understand anything about how their bodies will handle it," he said. "They have a time frame and they want to get blotto before they go in." 
 
 Medical staff and more than 70 police officers were assigned to the event, including an underage-enforcement detail hired through a state Department of Transportation grant, Foley said. 
 
 The underage-drinking arrests were made in the parking lots surrounding of the concert, which featured headliner Chance the Rapper. Foley said about 21,000 people attended the concert. 
 
 "The fan base last night appeared to be in the late teens and early 20s," he said. "Tailgating, partying and excessive alcohol consumption was extremely prevalent." 
 
 Brancato said there were more patients Friday night than he's used to seeing after a concert, with conditions ranging from mild slurring and unsteadiness to severe intoxication. 
 
 He acknowledged that 90 patients out of thousands of concertgoers represent a small minority of out-of-control drinkers. But that makes it no less dangerous, Brancato said, noting that some of Friday's patients were found unconscious. 
 
 "You never know what else could happen if a patient is so compromised they can't protect themselves," he said. "It's just bad in every way." 
 
 Hartford police held a meeting Saturday to discuss plans to prevent such a high number of alcohol-related issues in the future, but Foley said there was nothing further to release Saturday afternoon. 
 
 He did, however, urge parents to be aware of the environment their teenagers encounter at such events. He posted several videos of tailgating outside the concert on Saturday night, writing, "Parents: Did you drop your teen off at the concert tonight? This is what it looks like." 
 
 A Lady Antebellum concert was scheduled at Xfinity Theatre for next Saturday night — and underage drinking enforcement will continue — Foley said the atmosphere should be calmer. 
 
 Xfinity Theatre did not respond to a request for comment. 
 
 Those charged with underage drinking, most of whom were issued "promise to appear" summons, are scheduled to appear in Community Court in Hartford on Tuesday, Wednesday and Thursday, Foley said.
– First responders probably aren't among those who enjoyed Chance the Rapper's show in Hartford, Conn., where more than 90 people, many of them underaged, were hospitalized with severe intoxication. It was a "busy night," per deputy police chief Brian Foley—so much so that CNN reports that the town's ambulance provider had to call in help in ferrying patients to hospitals in neighboring towns. "When it's at this level, you're tapping into all your resources in the area," fire chief Raul Ortiz tells the Hartford Courant. "A typical concert is around 20-30 transports. Sixty would be very bad. We had 70 once and 90 last night," Foley says. Foley added that cops gave out 50 referrals for underage drinking, and that "additional steps will have to be taken to address these issues."
