Three people are dead and a fourth is in critical condition following what appears to be an attempted armed robbery early Friday morning at the University of Alberta in Edmonton, according to police.
Tactical officers and canine units are now at the scene of the shooting at HUB Mall, which houses retails shops and student residences.
Student Ravedh Seeberath tells CBC News that he heard the shots while studying around 12:30 a.m. MT.
"As I was walking down, that's when about thirty tactical officers were rushing toward me, passing me with complete firearms ... the whole works, and police dogs," he said.
"That's when I went back to my books, grabbed what I could, and told the other ladies in that little study area that we should get out of there."
A tweet sent from the University of Alberta account says the mall has been locked down.
More to come.
