INDIANAPOLIS - The IUPUI campus is on lockdown after reports of a man with a gun on campus.
"IUPUI Alert! Man with long gun seen in lot at Barnhill and Vermont. Seek shelter," a text alert sent by the school just before 1 p.m. read.
Indiana University Purdue University-Indianapolis police said a student walking to her car said she saw a white man in a long, brown coat possibly carrying a rifle or shotgun.
He was standing by a green or gray sedan at the time, but the student ducked down and did not see where he was headed, police said.
The location is a parking lot near the dental school. Police said they had cleared the original parking lot and were searching nearby lots and buildings.
Professor Trevor Potts told 9 On Your Side's sister station, RTV6, that the mood was tense on campus.
"Everyone's doing a very good job of staying calm and staying inside," he said. "I think this speaks to those who would argue for guns on campus, I think this is a rationale for why this is not a good idea, myself."
Student Charlie Elliott described the scene via Twitter.
"We were in the nursing building, which is pretty close to Barnhill and Vermont … They've just moved us into an 'interior room' inside the hospital," he wrote. "It's us and about 4 other classes all jammed in this room, the anxiety is beginning to grow. Police were well armed and we are locked in this room."
Indiana University Health University Hospital and Riley Hospital for Children were both locked down.
Crispus Attucks High School, which is near the IUPUI campus, is also on lockdown.
