INDIANAPOLIS » Officials at the Indiana University-Purdue University Indianapolis are warning students to remain indoors amid police reports of an armed robbery near the Indianapolis campus.

The campus issued an alert shortly after 3 p.m. today. It says “a subject with a gun has been reported running toward campus” and urges students and staff to find a safe shelter and lock doors.
