CHICAGO -- Two violent robberies happened just blocks and days apart in the Loop sparking campus safety alerts to go into effect at Columbia College and Roosevelt University.
One of the robberies happened on November 9 near Michigan and Balbo. A mob of seven teenagers attacked two female victims.
The other robbery took place on Sunday night near Michigan and Congress. A large group of teenagers wearing sweatshirts and dark colored hoodies targeted two 18-year-old women and a 20-year-old man.
They attacked the victims around 8 p.m. on the 500 block of South Michigan Avenue. They knocked them down and took their belongings. At least one of the victims attended Columbia College.
A 16-year-old girl was arrested and charged in that attack.
Police are still searching for at least eight other teenagers.
It's not known if the two robberies are related.
Columbia College has a safety seminar planned on Thursday at noon in on campus.
Students at Columbia know to stay away from the dimly lit Grant Park at night.
"My one class ends at 6:30 I don't have any late classes because of that simple fact and it’s usually in this area. So it’s still scary," Jomari Mirana, a Columbia College student, said.
"I just make sure I’m with somebody [at night] so i’m not out alone. I just don’t want to risk that any time," Ryan Tucker, a student at Columbia said.
