A police officer was first hit by a vehicle and then stabbed by its driver on Saturday evening near Commonwealth Stadium, and four pedestrians were injured by a truck driven by the fleeing assailant.
A police officer in Edmonton, Canada, was stabbed and four civilians injured in two incidents officials are investigating as connected "acts of terrorism".
The U Haul truck eventually flipped over, and the driver was taken into police custody.
"The vehicle struck the police officer, sending him flying into the air 15 feet, before colliding with the police officer's cruiser again at a high rate of speed", Knecht said. The attacker then fled, and the officer was taken to hospital.
"To the best of our knowledge", he told reporters, "this was a lone wolf attack".
- Police found a Daesh flag in the vehicle.
Hours later, about midnight local time, Edmonton police stopped a white U-Haul at an impaired driving checkpoint, according to NBC News.More news: Panthers at Patriots time, TV schedule, live stream, odds and more

Police then released the suspect's truck through the windscreen which had been smashed in.
"The police cars just kept coming, they just kept coming", said Jaylene Ellard, who was out with a friend when the scene unfolded on the bar and pub-filled avenue on a crisp early fall evening.
"I am deeply concerned and outraged by this tragedy", he said in a statement.
A suspect has been arrested, and the police believe he acted alone, but authorities do not exclude that other individuals are involved.
The driver then got out of his vehicle and stabbed the uniformed officer several times, before fleeing on foot. Police followed the auto.
"We can not and will not let violent extremism take root in our communities".
Edmonton has been hit by a terrorist attack. In 2014, a man killed a soldier in Ottawa and stormed the parliament building with a rifle before he was shot. Police officers put themselves at great personal risk every single day on our behalf, and this attack is a stark reminder of the sacrifices they make for the public good.
