A male was rushed to hospital via emergency run after being stabbed multiple times on a York Region Transit bus on Monday afternoon.

Two suspects were at a bus shelter near Yonge Street and Royal Orchard Boulevard in Thornhill at around 1:15 p.m. when the bus first pulled up.

Police have not confirmed how quickly the stabbing transpired after the suspects boarded the bus, however the vehicle was stopped outside the same shelter on Tuesday afternoon, suggesting that it never actually left the area.

The suspects are believed to have fled the scene on foot, according to police. 

At one point police did set up a perimeter to search for the suspects but ultimately called off the search.

The male victim remains in hospital where he is listed in serious condition.

On Monday afternoon the bus remained on scene as forensics officers searched for evidence inside. Blood was also visible on the ground near the middle set of doors.
