SIU Police are warning people to take extra care in an area just north of campus, after a string of robberies over the last couple of weeks.
In an alert to the campus community, authorities say they're investigating at least four robberies - three of them involving a gun - in the area near South University Avenue, West Cherry and West College Streets, to South Beveridge.
The most recent robbery was Wednesday just before noon.
Police describe the suspect as a black male, 18-24 years old, about five-foot-eight with a thin build.
