Hamilton police were called to the McMaster campus Friday morning to respond to a threat made against the Institute for Applied Health Sciences (IAHS) building.

Police were contacted just after 9 a.m., according to Sgt. Terri-Lynn Collings, media relations coordinator with Hamilton Police Services, who did not go into details about the nature of the threat.

“Hamilton police responded, secured the building, staff and faculty and students were evacuated from the building, and … Hamilton police are still on scene and will continue to investigate,” said Collings.

The building was closed at around 10:15 a.m.

“Classes and activities scheduled inside that building have been cancelled for today,” said Gord Arbeau, McMaster’s director of community relations.

“Students, faculty and staff have been cleared and sent home for the day,” he said.

UPDATE: The IAHS building reopened on Saturday, with all scheduled events going forward as planned.
