An alleged set of terrorist attacks took place in Edmonton, Canada, Saturday night into early Sunday morning leaving four people and a police officer injured.

The first incident occurred shortly after 8 p.m. Mountain Time. A police officer was working traffic detail at a Canadian Football League Game when a car crashed through a set of barricades, striking the officer. The impact sent the officer “flying 15 feet through the air,” according to a Police statement. On the dashboard of the car, police said, was an ISIS flag. Edmonton Police Chief Rod Knecht told several news outlets the incidents are being investigated “as an act of terror” and that the attacker acted alone.

The driver of the car, a white Chevy Malibu, then got out and stabbed the officer multiple times. The stab wounds are not life-threatening. The man then escaped the scene on foot.

Later in the evening, a man was pulled over in a U-Haul truck at a police checkpoint, and he fled in his truck when an officer noticed the name on his license was similar to that of the owner of the Malibu. As the U-Haul driver fled towards downtown Edmonton, the driver attempted to hit pedestrians on the sidewalk, according to police. The U-Haul truck eventually flipped on a main road in Edmonton, and the driver was apprehended. Police believe the man, 30, was involved in both incidents and acted alone, but are investigating further. His name has not been released.

“It is believed at this time that these two incidents are related, based on evidence at the scenes, and actions of the suspect, at 12:38 a.m. today, it was determined that these incidents are being investigated as acts of terrorism,” said Edmonton Police Chief Rod Knecht in a press conference early Sunday morning.
