Officials are investigating possible acts of terrorism after five people were injured in two attacks late on Saturday night in Alberta, Canada.
A man attacked a police officer before running down four pedestrians as he attempted to flee the authorities in the Canadian city of Edmonton.
The unnamed man has been arrested and is being investigating for “acts of terror”, police officers in Edmonton confirmed. They also said a black Isis flag was found in one of the vehicles used in the attacks.
The officer, who has also not been named, was manning a traffic check-point at a Canadian Football League when he was rammed by a white Chevrolet vehicle “flying several feet into the air” at around 8.15pm (local time) Saturday, Edmonton Police service chief Rod Knecht said in a press conference.
“A male, believed to be 30 years old, then jumped out of the vehicle and viciously attacked the Edmonton officer with a knife,” Knecht continued. The officer was stabbed “several times”, he said, before the suspect fled on foot.
Shortly before midnight, officials stopped a man driving a truck whose name matched that registered with the Chevrolet, and a police chase ensued during which the vehicle “deliberately attempted to hit pedestrians”, Knecht said.

The man was eventually arrested after his vehicle over-turned.

“It was determined that these incidents are being investigated as acts of terrorism,” Knecht said.
The officer's injuries are not believed to be life-threatening. The condition of the four pedestrians is not known, but all have been taken to hospital.
Knecht went on to state that the man – who was known to officers – was believed to have acted alone, but that investigations remain in their “very early” stages.
