This year's Lollapalooza festival in Chicago recorded the lowest number of arrests in five years, with a total of nine, down from 14 in 2023. The event, which was sold out at its 115,000-person capacity each day, also saw seven citations issued and 63 ambulance transports, marking a slight increase from previous years. The majority of arrests occurred on Saturday, with six incidents reported, while nearly a third of ambulance transports took place on Sunday. City officials credited improved security measures for the decline in arrests, which have decreased steadily since 2019. Alderman Brian Hopkins highlighted ongoing issues with fence-jumping and theft, suggesting enhancements to on-site reporting for theft victims in future festivals. The overall trend indicates a positive shift in safety and security at large events like Lollapalooza.
