One day after a report of a man with a gun on the University of Nebraska-Lincoln East Campus, police responded to a report of a man with two guns inside Oldfather Hall on Friday afternoon.

Lincoln and UNL police searched the building, which is home to offices and classrooms, for 30 minutes and found no gunman, nor any indication one ever was there.

UNL police said they got a 16-second call at 1:19 p.m. saying a man on the eighth floor was armed with two guns.

UNL spokeswoman Kelly Bartling said the call likely was a prank.

"We will investigate the call, but our first course of action when we receive a call with potential harm is to take every means necessary to ensure the safety of our students and staff," said assistant UNL police chief Carl Oestmann.

About a dozen police vehicles responded, and police set up a perimeter around the building and directed students from the area.

The campus was not put on lockdown, and school officials did not send an alert to students.

"We knew it was in one spot and our response was timely," Oestmann said.

Some students and staff were upset they were not alerted.
