CARBONDALE, Ill. (AP) - Authorities in Carbondale say they have two suspects in custody in connection with an armed robbery at a Southern Illinois University residence hall.

WSIU Radio reports that SIU Police issued a campus safety alert after two men with guns pushed residents back into a room on the 17th floor of Neely Hall on Wednesday. Investigators say the men were wearing ski masks. They took cash and a cell phone before escaping down the stairs.

Students were urged to lock their doors after the incident, but police stressed the campus wasn't on lockdown.
