Two attacks that took place in Edmonton, Canada on Sunday have been linked to a single suspected terrorist by local authorities, after a man who was seen driving his vehicle into a police officer, then stabbing him, later went on to drive a truck into at least four pedestrians during a chase from police.

At approximately 8:15 pm local time, the suspect drove a white Chevrolet Malibu into a traffic barricade law enforcement had put into place for an Edmonton Eskimos football game, hitting Officer Mike Chernyk of the Edmonton police, who was standing between the barricade and his cruiser.

It was military appreciation night for the Edmonton Eskimos, who play professional American style football in the Canadian Football League.  The game, which saw the Eskimos playing against the Winnipeg Blue Bombers, included Canada’s chief of defense staff, Gen. Jonathan Vance, conducting the pregame coin flip, and had hundreds of Boy Scouts in attendance.

“The vehicle struck the police officer, sending him flying into the air 15 feet, before colliding with the police officer’s cruiser again at a high rate of speed,” Chief Rod Knecht of the Edmonton Police Service said.
