Police have confirmed 10 people are dead and 15 are injured after a van rammed into a crowd of people walking on Yonge Street in north Toronto on Monday afternoon.

Alek Minassian, a 25-year-old man from Richmond Hill, Ont., is the alleged driver in the incident and is in police custody. He was arrested by Toronto police without any gunshots fired.

Minassian is believed to be responsible for hitting pedestrians with a white van in a busy part of the city. The suspect allegedly hit pedestrians on a one-kilometre stretch of Yonge Street near Finch Avenue, driving on the sidewalk and against the normal flow of the traffic at times, Toronto Police Chief Mark Saunders told reporters with high-ranking officials by his side.

“It’s very clear, just from a general perspective, to say the actions definitely looked deliberate,” Saunders said, adding the suspect is not believed to be known to Toronto police.

“We don’t rule out anything,” Saunders replied when asked if police are ruling out terrorism as a possible motive. “It is early — we’re not excluding anything.”

Saunders insisted “the city is safe” and police are not believed to be looking for any other suspects at this time. Toronto Police Services first tweeted about the incident being reported just before 1:30 p.m. ET.
