I was driving along the A96 towards Kintore at the Blackburn roundabout when a Stagecoach bus Reg No: V701 P/D SA was behind myself. I stopped at the roundabout as I thought a car was turning right, at which point I was rammed from behind (please see photographs provided), I was about to get out of my car when I was rammed again and pushed onto the roundabout by the Stagecoach bus Reg No: V701 P/D SA which then drove away without stopping and straight on towards Kintore at around 15:45. I then followed the driver and once I caught up to him I could see that he was dark haired around 30 years old talking on his mobile phone with his right hand and steering the bus at about 50mph with his left hand and a blonde woman mid 20's standing next to him still while driving talking to him.
