CHICAGO (CBS) — Police on the University of Illinois at Chicago campus have issued an alert, after a student was robbed and knocked unconscious earlier this week.

As WBBM Newsradio’s Mike Krauser reports, the alert says the student was off campus, walking between 8:30 and 9 p.m. Tuesday in the 400 block of South Green Street on the edge of Greektown. He was approached from behind by an unseen of offender, who placed something against the back of his head and demanded money, the alert said.

The student handed over his wallet, but the robber hit him in the head, anyway, and he passed out, the alert said.

It is not clear how long the student was unconscious on the sidewalk, but when he came to, he realized he had been struck.

He made his way to nearby Rush University Medical Center, where he was treated for a head injury, and interviewed by UIC and Chicago Police.

News of the attack and robbery did not go unnoticed on campus. Students say they’ll try to be more vigilant.

“I think it is a safe campus. It can happen anywhere and unfortunately it has happened here, but I think they’re trying really hard to make sure it doesn’t happen,” Shannon Brown, a graduate student in social work, tells CBS 2’s Marissa Bailey.

UIC police advise anyone to hand over whatever an armed robber asks for, as the student did. They also advise that students, faculty and staff report any suspicious activity to police.

Anyone with information on the Tuesday night robbery is asked to contact UIC police, at (312) 996-2830.
