The Chicago Police Department released preliminary figures for the four‑day Lollapalooza festival, showing a total of ten arrests and sixty‑seven concertgoers who required ambulance transport to hospitals during the event.
All ten arrests occurred during the first three days of the festival, which ran from July 31 through August 2, 2026, in Grant Park. No arrests were recorded on the final day of performances.
Emergency medical services responded to a variety of incidents, transporting sixty‑seven attendees to nearby hospitals for treatment. The department did not provide a breakdown of the medical issues involved, only the aggregate number of transports.
Lollapalooza is an annual multi‑day music festival that routinely attracts tens of thousands of visitors to Chicago’s Grant Park. Large crowds and the presence of multiple stages typically require a coordinated police and medical response to maintain public safety throughout the weekend.
Police officials described the released numbers as preliminary, indicating that final counts could be adjusted as additional reports are processed. The department emphasized that the figures reflect the overall scope of law‑enforcement and medical activity associated with the festival.
The festival concluded without further reported incidents, and organizers thanked city services for their support during the weekend.
