MONTREAL - A van ran over pedestrians in central Toronto on Monday, injuring as many as 10 people, police said.

“Update: unknown of extent of injuries, possible 8 - 10 pedestrians struck,” Toronto police wrote on Twitter.

A subsequent tweet said it was “too early to confirm the number of pedestrians struck or their injuries.”

Officers were called to the scene at 1:27 pm (1727 GMT), police said, without specifying whether or not the incident was deliberate.

According to local media, at least four people were killed in the incident and the vehicle had fled the scene. Late police arrested the driver.
