Lollapalooza Ends With 10 Arrests and 67 Hospital Transports

Higher hospital transports point to growing medical strain as the city assesses muddy-ground repair costs

Overview

  • City officials released final totals showing 10 people were arrested and 67 were taken to area hospitals over the four-day festival, and no ordinance citations were issued.
  • Officials provided a day-by-day breakdown: Thursday 4 arrests and 18 ambulance transports, Friday 3 arrests and 22 transports, Saturday 3 arrests and 16 transports, and Sunday 0 arrests and 11 transports.
  • Arrests were slightly lower than in 2025 while ambulance transports rose from 42 last year to 67 this year, the highest level reported since 2022.
  • Heavy rain on Saturday forced multi-hour delays, left large parts of Grant Park muddy, and prompted organizers and the city to begin assessing cleanup and repair needs without a cost estimate yet.
  • The festival sold out each day with 115,000 tickets per day, a crowd size that officials and medics say increases pressure on security and medical response and could affect final cleanup and recovery plans.
