University of Chicago students were given warnings by police Monday after three students were robbed at gunpoint Sunday night in two separate incidents.
At about 11:35 pm, two students walking at East 57th Street and South Dorchester had their cellphones taken by a male armed with a handgun, the school said.
About 30 minutes later, three males, one armed with a gun, robbed a student sitting in the Main Quadrangle on campus. The suspects took the student's cellphone and book bag before fleeing, the school said.
None of the victims was injured in the robberies.
Police are reviewing video footage for potential evidence. It is unknown whether the robberies were connected.
