Lollapalooza ends with 10 arrests

Chicago officials said Lollapalooza ended with 10 arrests and 67 ambulance transports over four days in Grant Park, a tally that left arrests below last year’s total but pushed medical removals higher. The figures were released Monday, August 3, by the city’s Office of Emergency Management and Communications, according to local reports. (chicago.suntimes.com) EDM.com and other outlets later identified some of the individual cases, including an alleged unauthorized drone flight and a backstage assault. Heavy rain also disrupted the festival’s third day and left much of Grant Park muddy through the weekend. ### Where did the 10-arrest figure come from? The City of Chicago’s Office of Emergency Management and Communications reported Monday that 10 people were arrested during the July 30-August 2 festival and 67 attendees were taken to nearby hospitals. (chicago.suntimes.com) The city’s pre-festival advisory had said Lollapalooza would run daily from 11 a.m. to 10 p.m. in Grant Park and draw hundreds of thousands of people to the lakefront. NBC Chicago and Fox 32 said the 10 arrests were preliminary police figures and that no arrests were reported on Sunday, the festival’s final day. Chicago Sun-Times reported the arrests were nearly evenly split across Thursday, Friday and Saturday. (chicago.suntimes.com) ### Which arrests drew the most attention?

Chicago officials reported 67 ambulance transports this year, compared with 42 during last year’s festival, according to the Sun-Times. Fox 32 also reported 67 people were taken by ambulance to nearby hospitals and said arrests were down from 2025 even as medical incidents increased.

Barrett Media reported that heavy overnight rain forced organizers to delay Saturday gates and that crews pumped water from flooded sections of South Grant Park before reopening. NBC Chicago said the festival’s grassy surfaces became water-logged and muddy for the second half of the event. EDM.com described the weekend as muddy and said the higher medical-transport figure came across the festival’s four-day run.
