Hundreds of teens crowded in the streets, fistfights, tasers, and a gunshot; that was the scene Friday night in the Streeterville neighborhood in downtown Chicago.

One alderman is renewing his call for an earlier downtown curfew for teens to help prevent the violence.

From his building's rooftop in Streeterville, Lukasz Dusza has seen the best and worst of Chicago.

"There's a reason we love it, and it's everything that's around here," he said.

Friday night, he saw hundreds of teens take over the streets below.

"Right behind this building was when the gunshot rang out," he said. "It's something you just don't see, and it's sad that we're seeing it right here."

Police said officers were on patrol around 9:40 p.m. in the 400 block of North Cityfront Plaza Drive, near the intersection of Columbus Drive and Illinois Street in the Streeterville neighborhood, when they heard gunshots and saw a large group fleeing the scene. 

Officers found a 15-year-old boy on the ground with a gunshot graze wound to his leg. He was taken to Lurie Children's Hospital, where he was listed in good condition.

Meantime, Lukasz captured video of a teen armed with a stun gun.

The incident happened in the same area where a tourist was shot near the AMC River East movie theater earlier this month.

"Two weeks ago, at that corner, a woman was shot visiting from Connecticut," Dusza said.

About an hour before the shooting in Streeterville, police said an 18-year-old man got into a fight with a group inside a store near State and Washington streets in the Loop. He was stabbed in his back before the group ran from the scene. He is also recovering in the hospital in fair condition.

After the shooting earlier this month near the movie theater, Ald. Brian Hopkins (2nd), whose ward includes much of Streeterville, and who chairs the City Council Public Safety Committee, said he planned to try again to urge the City Council to consider a curfew change for teens downtown – from 10 p.m. to 8 p.m.

"We've never seen this happen this early before, and with two consecutive gunfire incidents related to these teen takeovers, it's time that the entire city started treating this as the serious life-threatening situation that it is," he said.

Hopkins first introduced his proposal last year, but it has been stalled in committee, amid opposition from Mayor Brandon Johnson.

"The police tell us that they could use this tool effectively. So if the police are asking for help trying to quell violent takeovers of our streets, we should give them that help," Hopkins said.

In a statement Saturday night, Johnson said, "No one wants to see the reckless and dangerous behavior that was exhibited last night and we are not going to tolerate that in our city." 

"Our police department is currently investigating the incident, and all those who have caused chaos will be held accountable," the mayor added.

However, Johnson said he opposes the earlier downtown curfew "because it would just displace these young people into the nearest neighborhood."

"It's not productive to shift the problem to the next community over. What we have to do is enforce the current citywide curfew law that we already have in place before we consider additional measures," Johnson said. "And we need to make sure that there are additional safe spaces for our young people this spring and summer. We are calling on our City Department, our civic community, our business community, our philanthropic community, and our faith community to lean in and keep working with us to create even more spaces and opportunities for our young people this year."

A day after Friday's teen takeover in Streeterville, the mayor was hosting the 4th annual My CHI. My Future. Teen Bash at Navy Pier.

The event includes a resource fair to connect teens to jobs and opportunities to keep them occupied this summer.

"I feel like this could help a lot of kids in the neighborhood get off the streets. You know, try to make their life, try to change their life for the better," said 16-year-old Carlton Thomas.

Thomas said he heard all about Friday night's incident in Streeterville, but he wasn't among the teens downtown.

"I'm happy I didn't go," he said.

Thomas said an earlier curfew might've helped – a little.

"A curfew would be good. I don't think it's going to stop, like, everything that's happening downtown, but it'll kind of like reduce it," he said.

Hopkins said he expects a vote on his curfew ordinance in April.
