Initial investigations suggest the 23-year-old victim was driving a white Mercedes outside of a business located on Pine Mountain Road, when he was confronted by two vehicles, a black Audi A3 hatchback and a white Nissan Patrol.
A group of four males exited the vehicles and allegedly assault him, pursuing him across the street.
The 23-year-old man collapsed on the corner of Brigadoon Street and Pine Mountain Road.
Emergency Services were notified and immediately attended, rendering first aid to the man on scene.
He was pronounced deceased a short time later as a result of his injuries, which included multiple stab wounds.
