The groups began to gather about 5 p.m. along the Washington Street corridor, between Chicago and Van Buren avenues, police said.
Police were present throughout downtown during the gathering.
Police said as the night went on, several teens and young adults violated state laws and local ordinances.
Crowds were dispersed by about 11 p.m.
A 17-year-old Plainfield boy was arrested for battery and cited for crossing a roadway outside of a crosswalk; a 15-year-old Bloomington boy was arrested for obstructing identification and cited for crossing a roadway outside of a crosswalk; a 17-year-old Bolingbrook boy was arrested for battery, assault and illegal possession of cannabis and tobacco by a minor; a 17-year-old Aurora boy was arrested for obstructing identification and criminal trespass to state-supported land; and a 17-year-old Romeoville boy was arrested for disobeying a peace officer and cited for crossing a roadway outside of a crosswalk, police said.
A 23-year-old from Naperville was arrested on four outstanding warrants, for obstructing a peace officer and was cited for crossing a roadway outside of a crosswalk; an 18-year-old from Aurora was arrested for obstructing identification and cited for crossing a roadway outside of a crosswalk; an 18-year-old from Romeoville was arrested for attempted aggravated assault on a peace officer and cited for crossing a roadway outside of a crosswalk; and an 18-year-old from Romeoville was arrested for battery, obstructing a peace officer and cited for crossing a roadway outside of a crosswalk.
Nearly 36 citations were issued, police said.
"We've been very clear on our stance. We want people to come to our city, patronize our businesses, and enjoy all the amenities Naperville has to offer. But if you break the law, there will be no warnings; there will be no second chances. We've tried that approach, and it was met with a lot of disrespect and lawlessness. So, as last night proved, we will not hesitate to make arrests and issue citations for breaking the law. I want to thank our officers for their incredible teamwork and professionalism, the additional agencies that responded to assist, and our community for their trust as we work to keep Naperville safe," Police Chief Jason Arres said.
In Chicago, nonprofit groups and aldermen have been working to prevent so-called teen takeovers, which can at times turn violent.
