The video showed large groups of teens running through the streets and even jumping on cars. It was happening in the northern part of the city's downtown area. At one point, a video of the chaos was taken just blocks from Illinois Governor J.B. Pritzker's mansion, prompting police to stage snow plows to protect the area, according to CWB Chicago. Chicago police said they responded to a crowd of "youths" which were dispersed from a popular beach. They said no arrests were made and no injures were reported.
