Two people were arrested Thursday, the opening day of the festival, and 10 more people were arrested Friday, according to Melissa Stratton, a spokeswoman for the city's Office of Emergency Management and Communications. Another 29 people were issued citations - almost all for fence jumping and trespassing - during the festival's four-day run.

Additionally, 128 people have been transported to hospitals for treatment by paramedics, Stratton said. A total of 49 people were transported on Sunday, 57 on Saturday, 56 on Friday and 72 on Thursday.

Chicago police say they recovered over 60 cellphones after arresting a suspect who is believed to have been stealing mobile devices from concertgoers at Lollapalooza over the weekend.

The HomePod firmware has offered a bit more information about Face ID that makes it seem like a viable Touch ID replacement. When reports started suggesting that Apple might drop Touch ID support altogether, people were skeptical at first.

Last year, 12 people were arrested over the course of the festival - the first time it was extended to four days - while 34 people were arrested over three days in 2015.

Concert organizers encouraged anyone whose phone was stolen to report it on the event's website, lolla.com/lostfound, where festivalgoers can also search the inventory of unclaimed items.
