'Teen Takeover' terrorizes Chicago as hundreds of teenagers ...

Hundreds of teenagers stormed the streets of downtown Chicago, smashing car windows, attacking bystanders and sending panicked tourists running from the sound of gunfire.

"Where are their parents at? That's my question," a woman who identified as a Chicago native told Fox 32 as the unruly scene played out in downtown Chicago on Saturday night.

Fox 32 cameras captured video of teenagers crowding the streets and police seeking to restore order to the area.

Large groups of teens were seen blasting music from Bluetooth speakers and roaming in front of traffic, with some attempting to gain access to the city's Millennium Park, which is off-limits to those under 21 after certain hours, and the downtown Art Institute. 

Some teens in the group began jumping up and down on cars, smashing windows and attacking people inside. One woman told Fox 32 her husband was attacked from the driver side of his vehicle and beaten after a group of teens jumped up and down on the couple's windshield. The man was taken to a local hospital for treatment.

Fox 32 reported that the chaos appeared to be another "Teen Takeover" of the city that was planned on social media, noting that a similar scene played out in Chicago last year.

"I understand kids having a good time, but this is simply bad parenting," the Chicago native witness told Fox 32. "We have to do better as parents. Our kids should not be out here."

Chicago police did not immediately respond to a Fox News request for comment.
