A shocked motorist looked on in horror as a road rage incident unfolded in from of him in Dundee at the weekend.
Dale Cairns, 24, a support worker from Perth, said he had been sitting at a car at the traffic lights at the Claypotts junction on Saturday when trouble kicked off.
Dale said: “A red car pulled up in front of the black BMW in front of him.
“Straight away the guy in the red car got out and went to get the attention of the people in the BMW.
“I think he got a shock however, when four young lads got out of the car.
“The driver of the red car then seemed to change his mind about confronting the boys in the car and made his way back to his own car.
“However the lads got out and followed him. What happened then looked pretty shocking.
“You can clearly see the man’s head being slammed by the car door as it was pushed shut against him.
“After that the boys got back into their car and everyone took off.
“I don’t know if anyone called the police but I certainly didn’t see any arriving before we drove away.
“The registration number of the BMW is very clear in the video I took so it won’t take much to trace them.”
Dale said it all happened really quickly.
He said: “I got the impression that something must have happened further back the road before the cars got to the traffic lights that made the driver of the red car angry and decide he wanted to tackle the blokes in the BMW.
“It looked like a real case of road rage but I have no idea what was behind it.
“It escalated really quickly and got pretty physical.
“I think the guy who got hit must be pretty sore.
“He took a blow to the head with the car door and he could have ended up with concussion or anything.
“It was pretty shocking to see to be honest.”
Dale said he had been contacted by friends of those involved asking him to take the video down.
“They have seen it and obviously are upset that the whole incident was filmed,”
Police Scotland spokesman said: “We have not been made aware of this incident, however would ask anyone who directly witnessed it to contact us on 101 so we can make relevant inquiries.
