A Victoria University spokesperson said staff and students who were in Rutherford House had all been evacuated, and were now a safe distance from the building.
She said they didn't have any information on what type of threat had been made, as they'd only just become aware of the bomb scare themselves.

The campus is home to the School of Management and the Schools of Government, Law, Economics and Finance, Information Management, Marketing and International Business and Accounting and Commercial Law.
