Aug. 5 (UPI) -- Police in Ontario shut down multiple roads in the King area when a pair of bison broke through a fence and escaped from their pasture.

York Regional Police issued an alert on social media Monday warning drivers in the area to avoid the area of Keele Street and Davis Drive due to the presence of loose bison in the area.

Local residents were warned not to approach the animals.

Garrett Mac Sweeney, the farm's owner, said the bison are currently in their mating season, which makes them more aggressive.

"That was quite scary," Mac Sweeney told CityNews. "We noticed they were very aggressive this past week and the week before."
