Police were called to Highway 7 – west of that city around 2:00 a.m. They learned one of the motorists involved had driven away from the collision scene without sharing any information.
The second motorist followed and the two vehicles eventually stopped at 22nd Street West and Betts Ave in Saskatoon.
Both drivers became involved in an argument with one of the drivers retrieving a long-barrelled firearm from his vehicle and pointing it at the second driver.
The armed suspect then took off on foot. The suspect is described as a 40-year old, wearing a black toque, and a black jacket. It is believed he has a .22 caliber rifle.
No shots were fired and no one was injured. Damage to both vehicles as a result of the collision was minimal.
Police have impounded the vehicle the suspect was driving and the investigation is continuing.
