Nearly two dozen people who attended an electronic dance show, featuring Swedish DJ Avicii, have been hospitalized in Boston.
Police say they showed up to TD Garden intoxicated, Wednesday night.
"I don't know. I think it was drunk, might've been molly. I don't know. You never know with these people. They're crazy," said one concertgoer.
22 people had to be rushed to the hospital. A dozen more were under evaluation.
"There was one kid, he took four cops to get him down," added another person. "He was on something, I have no idea."
Two people died over the weekend at a Las Vegas music festival, also attended by Avicii. Authorities said it could take several weeks to determine what caused the deaths at the Electric Daisy Carnival.
