    Hours after Chicago's biggest music festival came to an end, city workers began the clean-up process from more than 400,000 music fans that made their way across Grant Park over the weekend.

    The 25th annual Lollapalooza was extended from three to four days this year for the first time, and an estimated 100,000 people attended each day from Thursday through Sunday.

    Multiple people were arrested and hundreds were taken to area hospitals for medical treatment during the festival's first three days, according to the City of Chicago's Office of Emergency Management and Communications.

    On Thursday, July 28, two people were arrested, one cited, and 84 taken to area hospitals, OEMC spokesperson Melissa Stratton confirmed.

    On Friday, July 29, seven people were arrested, four received citations, and 79 were taken to local hospitals. Two of the arrests Thursday and Friday were for flying drones over the festival, Stratton said, which is not permitted. 

    On Saturday, July 30, three people were arrested, seven cited, and 56 taken to area hospitals, Stratton confirmed. Sunday's numbers were not immediately available, as the OEMC does not release information pertaining to arrests or transports until the following day. 

    In 2015, a total of 34 people were arrested and 238 were taken to hospitals for medical treatment throughout the three-day festival.

    While officials have not specified how many people arrested or taken to hospitals this year were underage, last year 88 of those receiving medical attention were intoxicated teenagers.
