A “flash mob” of some 200 Chicago residents swarmed Glen Ellyn’s Sunset village pool on Saturday afternoon, forcing their way past the entrance and assaulting the pool manager.

A video posted on Instagram shows a crowd pushing manager Christine Giunta-Mayer into the lap pool, which had been surrounded by the mob.

Sources tell DuPage Policy Journal that the mob arrived around 4:30 p.m.

Glen Ellyn Police arrived soon after and closed the pool.

A Sat. afternoon Facebook post by Patrick Sandusky reported the pool as “now closed.”

“The Sunset Pool has been overwhelmed by out of town kids,” he wrote. “Fireworks fired into pool. It’s a tik tok meet up / take over according to police I just spoke to.”

“Kids pushed (past) the gates. Lot of drinking and weed in the parking lot. 100s and 100s of kids. No joke. Pushed manager into the pool,” Sandusky wrote.

The Sunset Pool's non-resident admission rate is $15 for individuals 18-59.

On Sunday, Sunset Pool visitors were required to have a physical pool pass issued by the park district, sources tell DuPage Policy Journal.

Weed, Miller Lite, and "on the rocks cosmos"

Glen Ellyn teens present described a chaotic scene.

The flash mob brought in coolers with alcohol and speakers to play music.

"They were drinking and smoking weed and swearing a lot," a Glen Ellyn teen present at the pool at the time told DuPage Policy Journal. "Someone threw a lit cigar into the pool."

"I saw Miller Lite bottles and girls drinking on-the-rocks cosmos," the teen said. "They were taking people's stuff and moving it from their pool chairs."

The flash mob was originally planned for Naperville.

“We bringing (sic) 31st Beach to the burbs” read a Facebook advertisement promoting the event, scheduled for Naperville’s Centennial Beach, from 4:00 p.m. to 8:00 p.m.

“31st Beach” is a reference to 31st Street Beach on Chicago’s South Side.

Giunta-Mayer is also head coach of the Glenbard West Hilltoppers Boys’ Volleyball team.
