An Edmonton police officer was hit by a vehicle and stabbed multiple times, and four other citizens were hit by a U-Haul truck.
The events of Saturday evening first unfolded when the man crashed his Chevrolet Malibu into a barricade, sending a police officer directing traffic at a football game 15 feet in the air.
Here is what the Edmonton Police Service is saying about the stabbing of an officer Saturday night and a vehicle that struck four pedestrians.
Police in Edmonton, capital of the province of Alberta, said that an Islamic State flag was found in the vehicle that struck the officer. The suspect then jumped out of the auto, stabbed him and fled the scene on foot, police said. He added the suspect was taken into custody and being interviewed by police.
A terror inquiry is under way in Canada after a police officer was rammed by a vehicle and stabbed and four pedestrians were struck by a van. He said he didn't know the extent of the pedestrian injuries.
A few hours later, while fans filed out of the game and were re-routed around the crime scene, a U-Haul cube van was stopped at a checkstop north of downtown.
When police noticed that the name on the driver's license was similar to that of the registered owner of the white Malibu, the man took off toward downtown Edmonton, according to the police account.
When confronted, Knecht said the U-Haul sped off toward downtown with police cars in pursuit.
Knecht said the investigation was in the early stages, and urged Edmontonians to contact police if they see or hear anything suspicious.

Similarly, Washington also urged neighbouring countries to "reject unilateral measures and the use of force". Iraqi forces were also deployed on the border with Turkey as part of a joint exercise with Turkish troops.
- During the chase, police say the truck deliberately tried to hit pedestrians in crosswalks and alleys. "It's not critical", Knecht said of the injuries.
Trudeau said the Royal Canadian Mounted Police and the country's Integrated National Enforcement Team had joined the Edmonton police in its investigation.
Police say an ISIS flag was later found in the suspect's vehicle.
Pat Hannigan said he was across the street when he saw the truck flip over.
After that, Elgie said he still had a bar to run that was full of people.
Police believe the suspect acted alone, but haven't rule out involvement by others.
Social media photos of Jasper Avenue showed the U-Haul flipped on its side in the middle of the street.
A heavy police presence had blanketed Edmonton's inner city after the initial incident as the manhunt ramped up.
