Police investigate the scene of an armored-car robbery at the University of Alberta in Edmonton, Friday.

Three people were killed and one is in critical condition after a shooting at the scene of an apparent armed robbery at the University of Alberta campus in Edmonton, Canada early Friday, according to reports.

“It was an apparent armed robbery of armored vehicle and or vehicles,” police spokesman Scott Pattison told the National Post of Canada.

“The university was quickly put into lockdown, it has its own protocols and it remains in lockdown now,” he said. “It’s a crime scene so students are required to stay remain in their dorms.”
