9 people have been killed and 16 injured after a man drove a van into pedestrians in Toronto, police have reported.
The driver fled the scene of the incident but was arrested several streets away.
The arrest of the driver followed a tense standoff with police on the street.
Bystander videos appeared to show the driver pointing an object at the officers, who can be heard shouting at him to get down.
The man was then detained without any shots being fired.
Toronto deputy police chief Peter Yuen asked for witnesses to come forward and said there will be "a long investigation" to follow.
