Boston's TD Garden Cited After Dozens Hospitalized At Concert

Boston's TD Garden was cited Thursday for a license violation after dozens of people were taken to area hospitals after an electronic dance music concert at the venue Wednesday night.

Boston Police cited the venue for having intoxicated, underage patrons on the premises.

First responders treated as many as 80 people at the Garden Wednesday night — three dozen of those were taken to area hospitals.

Boston Police Chief William Gross says authorities do not believe the form of ecstasy that's caused overdoses at other concerts was involved.

"It didn't seem like there were any symptoms of the uses of molly, but it did appear that it was some type of illicit drug use along with alcohol consumption," he said.

Garden spokeswoman Tricia McCorkle says precautionary measures were taken, including limiting alcohol sales and providing areas for patrons to cool off.

"We continued our proactive policy to identify impaired guests, bring them to first aid for medical evaluation and transport when necessary," McCorkle said in a statement. "By following our policy, half of the affected guests were identified prior to entering the arena and were immediately treated."

Boston Mayor Marty Walsh says he wants to know more about what happened.

"We're gonna sit down, have a meeting with the licensing board and the commissioner, and we're going to see what the situation is and take appropriate action," Walsh said.

The Swedish DJ Avicii headlined the concert.

"Just hearing the awful news [about] tonight," Avicii tweeted Wednesday night. "[It's] a terrible thing, I [really] hope everyone is ok!"

Two people died over the weekend at a Las Vegas music festival attended by Avicii, one of the biggest names in electronic dance music. Authorities said Monday it will take several weeks to determine what caused the deaths of the Electric Daisy Carnival fans.

Police said nearly 800 people were treated for medical conditions and 25 were hospitalized during the three-night electronic music festival, which organizers said drew about 400,000 people at the Las Vegas Motor Speedway.

Festival organizers told police that 134,000 fans attended Friday, Saturday and Sunday night shows featuring pulsing lights, Ferris wheels, seven stages of music and DJs including Avicii, Diplo, Afrojack and Tiesto.
