EDMONTON, Canada—Canadian police on Sunday arrested a man whom authorities said they believe acted alone to carry out violent “attacks of terror” in the western city of Edmonton, injuring a police officer and four pedestrians with two vehicles and a knife.

A graphic surveillance video shows a Chevy Malibu hitting a police officer standing in front of a football stadium at about 8:15 p.m. on Saturday, sending him flying into the air. The driver gets out of the car and appears to stab the officer multiple times before fleeing.
