The school did go into lockdown.

“Chicago Public Schools (CPS) is working closely with Chicago Police Department (CPD) as we respond to a shooting near one of our high schools, just prior to the school’s dismissal bell. The school went on a lockdown while the CPD responded and that lockdown has since been lifted and students have been released. We will communicate any additional information with the school community. Our thoughts are with those individuals injured in this incident,” Chicago Public Schools said in a statement. 

It wasn’t clear if the injured juveniles were students.

No information was available regarding the suspect.

Speaking to CBS News, Jose Villanueva, a witness, said heard gunshots while waiting for his niece outside the school. 

“As soon as I parked here, I heard the shots. That’s about it,” he told the outlet adding that he heard “roughly three” shots.

“The kids were sitting over there having a good time. All of a sudden when they heard the shots, they went down. Since we heard the shots and everything, I figured out that the school was on lockdown – which is what happened,” he added.
