EDMONTON, Alta. – Five people, including an officer with the Edmonton Police Service (EPS), were injured in two related incidents that police are deeming acts of terrorism on the evening of Sept. 30. At about 8:15 p.m. that day, a man drove a white Chevrolet Malibou through traffic barricades near Commonwealth Stadium, according to an EPS media release. The vehicle struck a uniformed officer, and the driver then exited the vehicle and stabbed the wounded officer numerous times before fleeing on foot, police said. The officer was sent to a hospital with various injuries. The suspect went on to hit four civilian pedestrians with a U Haul truck later that night, police said. EPS officers have arrested a 30-year-old Edmonton resident in connection with the attacks. “Currently, we believe this is an individual who acted alone, although the investigation is in its early stages,” EPS chief Rod Knecht said in a press statement. “We are urging all Edmontonians to be vigilant and aware of their surroundings.” Alberta Premier Rachel Notley called the province’s first responders “incredible people” in an Oct. 1 statement responding to the attack. “Thank you to each and every one of our police officers, paramedics and firefighters who put their lives on the line to keep us safe,” she said.
