CHICAGO — An unruly crowd in the West Loop disrupted neighbors with fireworks and car stunts overnight.

It’s the second time in July that a large early morning gathering turned into a significant disturbance, with an officer falling victim to injury.

UPDATE: Donuts, drag racing & drifting: Ordinance aims to put the brakes on car stunts

Video obtained by WGN News shows multiple cars drifting in the downtown roadway. One day later, skid marks remain at the intersection of Clinton and Monroe.

Videos on the Citizen app show vehicles and people gathered at the intersection as drivers do donuts and drift.   

A resident who lives in the area, but did not wish to be identified, says the noise awoke her.   

“I heard a lot of screeching,” she said. “It was really loud.”

According to police, a firework struck and injured an officer. A 17-year-old was arrested and charged with one felony count of aggravated assault on a police officer.

Two weeks ago, on July 2, a similar scene occurred in Portage Park. A police officer was taken to the hospital for minor injuries when a crowd attacked a squad car.

It’s startling scenes from the past that residents say they don’t want to happen in their area. 

“I work second shift, so all I want is to get home,” the woman said. “I don’t want to be stuck in traffic when I’m super tired. I want to go to sleep. You pay for comfort down here. It’s uncomfortable to have to go through that.”
