Hundreds of young people filled the streets and sidewalks in Chicago last week in what Mayor Brandon Johnson is calling "teen trends" that he warned can turn deadly.
Video, obtained by Fox News from ChitownCrimeChasers, showed the teens filling streets and sidewalks on March 30, clustering around parked vehicles and moving through intersections.
Other footage from that night captured different individuals dancing and socializing in the city's streets, while other moments showed people climbing on cars and brief altercations within the crowd.
In Hyde Park, residents say the March 30 takeover lasted for hours late into the night.
One resident, Jason Hale, said his car was among roughly 30 affected by crowds in Chicago that night.
"Yeah, it’s bad. The hood is messed up, terrible. A thousand worth of damage, dents everywhere, footprints everywhere," Hale told all parents. Check in with your children. See where they plan to be this weekend. Please, do not allow your child to attend any of these trends this weekend."
"They're unsafe, and they can turn deadly. Our police officers will be out enforcing the city's 10 p.m. curfew," he said.
Some residents say the repeated gatherings are raising concerns about safety and quality of life.
Hale said the incident has prompted him to reconsider staying in the city.
"Your kids should not be out here… I had parents who guided me," he said. "And these parents, they just let them run rampant."
