The statement continued, “SJFD immediately requested an Ambulance Task Force, two additional advanced life support fire units, and a Battalion Chief to manage the incident and provide additional medical resources. A total of 14 ambulances responded, and 14 patients were transported to local hospitals.” By 10:34, all ambulances and personnel had completed those transportations.
The department did not publicly announce why attendees had been hospitalized, but the local police department told NBC Bay Area that medical attention had been administered because attendees were suffering from “suspected alcohol intoxication and drug-related issues.”
According to SFGate, no concertgoers were arrested. The Chainsmokers’ next show is this Saturday (September 12) at Las Vegas’s Encore Beach Club. They have yet to make a statement on the incident.
