Downtown chaos: Chicago police arrest 21 juveniles, two officers are injured, bus driver attacked

A gunshot wound, 21 juveniles arrested, two officers injured, one bus driver attacked, nine curfew citations: It was a busy Saturday night for Chicago police in the downtown area.

Chicago police arrested 21 juveniles downtown on Saturday night after calls came in of a large group. An additional nine juveniles were cited for curfew violations.

Police said one juvenile had a gunshot wound to the arm and was taken to the hospital. 

Two officers were injured, including one who had a broken arm.

Two replica guns were recovered.

A CTA bus driver was also attacked in the Loop on Saturday night; a 15-year-old was arrested.

"My understanding is this was a flash mob incident where they went on social media and told people to come downtown," said CTA union president Keith Hill. "Half of the people that assault drivers aren't afraid of being arrested. They're not afraid of the police. Nobody deserves to come to work and get assaulted."

Chicago police said that they had "sufficient resources deployed to manage the crowd and ensure public safety."
