Dec 15 (Reuters) - A person with a gun has been reported running toward the Indiana University-Purdue University campus in Indianapolis, and students are being urged to take shelter, according to the school's web site.

Students and faculty were advised in an online alert to take safe shelter and lock the door if possible, remaining in place until an "all clear" is given. (Reporting by Mary Wisniewski; Editing by Andrew Hay)
