Boston EMS and other emergency personnel established a command center at the TD Garden after a “mass casualty event” due to alcohol and drug use at a concert Wednesday night.
36 people were transported by ambulance to area hospitals and 50 others were treated at the scene, all with minor injuries, according to the Associated Press.
The Boston Globe reported that the response was heavy after officials declared the incident a “Phase 2 Mass Casualty Incident,” which means approximately 30 people needed to be hospitalized.
Boston EMS Deputy Superintendent Mike Bosse said all of the people treated appeared to be between 16 and 25 years old.
Bosse blamed alcohol and drug use for the incident, but many concert goers attributed their dehydration to excessive heat inside the venue.
A spokesperson for concert promoter Live Nation said the majority of the people treated were still outside the venue and too impaired to get in.
Bosse said the TD Garden was cited for allowing some intoxicated concert goers to enter.
Swedish DJ Avicii, whose real name is Tim Bergling, was performing at the Garden Wednesday night. He tweeted after the concert that he was concerned for those who were impacted.
During his concert last week in Toronto last week, 29 people were taken to hospitals for “illnesses related to alcohol or drugs,” according to The Toronto Star.
