Three people have been killed and one injured in a shooting after midnight in Edmonton, Canada, police say.

They were killed in an apparent robbery of an armoured vehicle, police said. The suspects have not been found.

The shooting took place on the University of Alberta's campus. The university has tweeted that no students were harmed in the incident.

The victims have not been identified but worked for security firm G4S Cash Solutions, the Globe and Mail reported.

The incident took place near a cluster of bank machines at the HUB mall, which also included student residences, the newspaper added.

Two men and one woman died from their injuries and another man is in hospital in critical condition, police said.

"The university was quickly put into lockdown," police spokesman Scott Pattison said. "It's a crime scene, so students are required to stay in their dorms."

A statement on the university's website said: "The university is saddened about those who lost their lives last night and we extend our condolences to their loved ones."

The university said the rest of the campus was operating normally.
