EDMONTON -- Police have issued several warrants in Alberta and the Northwest Territories for the arrest of a man they believe to be connected to an assault at the Southgate LRT transit station in late May. Edmonton police issued warrants for the arrest of 36-year-old Brent Cardinal of Hay River, N.W.T. Thursday evening for aggravated assault, robbery, and various breaches of conditions. At approximately May 26 at 2:30 a.m., police say Cardinal and two other men were evicted for loitering by Edmonton Transit System peace officers. The group was standing outside the locked west entrance of the LRT station when they gestured for a male to open the door for them.
