At least five people are injured, following a series of incidents in Edmonton, Canada which police are investigating as possible acts of terrorism.
According to police, an officer controlling traffic at a Canadian Football League game was first struck at high speed by a car, then attacked with a knife.
A van then went on to hit at least four pedestrians and was arrested two hours later after a police chase.
Police reportedly found an Islamic State flag in one of the vehicles.
Edmonton Police Service Chief Rod Knecht said the officer and his vehicle were rammed by a white Chevrolet Malibu outside Alberta’s Commonwealth Stadium at 20:15 local time.
The driver then got out of his vehicle and stabbed the uniformed officer several times, before fleeing on foot. The officer was taken to hospital but his injuries are not thought to be life-threatening.
According to Knecht, the information about the registered owner of the vehicle was broadcast to patrol officers and shortly before midnight a man driving a U-Haul rental van was pulled over at a checkpoint after his name on documents was said to be “very similar” to the one police were searching for.
“The U-Haul truck then immediately fled the scene, and was pursued by police officers toward downtown Edmonton,” the police chief said.
He said the truck “deliberately attempted to hit pedestrians” during the police chase.
The driver, a 30-year-old male, was arrested after his vehicle overturned in a police chase. Police said the arrested man was known to authorities.
The condition of the four injured pedestrians is not yet known.
