The University of Indianapolis' campus was briefly evacuated Thursday afternoon as authorities investigated a possible bomb threat.
The school told all students to immediately evacuate all campus buildings and leave campus in an alert tweeted just before 3:30 p.m.
By 4 p.m., the university said all campus buildings had been swept and the all-clear was given to re-enter buildings.
The school's president Robert Manuel told students "officers found no evidence iof a bomb or suspicious materials around campus."
Evening classes remained canceled, the school said.
"We reviewed this threat which we received about 4:00 p.m. and after consultation with law enforcement found the threat credible," Manuel said in a message to students. "It was our decision that an evacuation was necessary. I am sorry for the disruption that this caused to our classes, events and your schedules, but thought the threat was credible enough to issue the evacuation."
