UPDATE: A spokesperson for TD Garden tells E! News in a statement: "We take this incident very seriously and our thoughts are with the affected guests and their families. We implemented increased precautions such as restricted alcohol sales, additional security and provided two cooling off areas for guests, in addition to the building maintained at normal temperature. We continued our proactive policy to identify impaired guests, bring them to first aid for medical evaluation and transport when necessary. By following our policy, half of the affected guests were identified prior to entering the arena and were immediately treated."
Jacqueline Peterson, a spokesperson for Live Nation, tells E! News: "While this is still a developing situation, based on early reports from the venue it appears the majority of the transports were people outside the venue who were too impaired to be allowed inside the venue and access to the concert. Out of an abundance of caution they were transported for medical evaluation and assistance."
A source tells E! News, "Avicii's team was unaware of what was happening because most of this happened outside the venue. They heard about it from news reports or saw the transport when they were leaving the venue...The show was not stopped. Avicii has played more than 1,000 shows In the last 3 years, and not one has EVER been cancelled due to reckless behavior, drugs or alcohol."
A spokesperson from Boston EMS confirmed that 36 individuals were hospitalized, the first transport being at 9:30 p.m., telling E! News in a statement: "Boston EMS transported 4 patients from outside the TD Garden on Causeway Street to area hospitals last night...TD Garden contracts with a private ambulance company for events–that company transported 32 patients from the venue, for a total of 36 patients. Due to patient confidentiality, we cannot release information on cause of illness or injury."
At least 36 people attending Swedish DJ Avicii's concert at Boston's TD Garden were rushed to area hospitals Wednesday night.
Per NBC News, authorities said the injuries were from dehydration and suspected drug and alcohol abuse. Fifty more partygoers were reportedly treated at the scene, and according to NBC affiliate NECN, the ages of people requiring medical assistance ranged from 16 to 25.
"I think it was dehydration or something like that but, I'm not too sure, but there has been a lot of ambulances showing up and taking some people away on stretchers," one concert-goer said.
Another described the scene to NECN, saying, "People were jumping up-and-down, some people tripped, some people may have hurt their ankles. And of course they need ambulances to help them out."
Fortunately, no one was seriously injured.
Understandably, though, Avicii (whose real name is Tim Bergling) was upset to hear of fans' sustaining injuries at his show. "Just hearing the awful news abt tonight," he tweeted Thursday morning. "Its a terrible thing, I rly hope everyone is ok! My thoughts go to those affected & their families."
