Police Scotland is seeking witnesses to what appears to be a road rage incident on the A75 near to Ramhill, Castle Douglas.
At around 11.15pm on Wednesday 14 December a 48 year-old van driver from Birmingham was driving east on the A75 when he was overtaken by an articulated lorry which pulled up sharply in front of him.
When the victim stopped behind this lorry, in his white Mercedes Sprinter van, the driver of the lorry alighted from his vehicle, approached the victim and began to assault him.
Nothing appears to have been said by the attacker and the victim as a result was left with a sore face and in a shocked condition.
The driver of the lorry then left the scene. The matter was reported to the police by the victim shortly afterwards.
Constable Callum Jardine at Castle Douglas said: “The only description that the victim was able to give regarding his attacker is that he was between 40 and 50 years old, stocky build with a beer belly.
“He was about 5’8” tall and had short grey hair and a goatee beard and moustache.
“He was wearing a red and white vertical striped t-shirt, jeans and safety boots.
“The victim received some cuts to his face as a result however did not require medical attention.
“We want to hear form anyone who may have been on the A75 near the Ramhill around this time to get in touch if they saw anything which might help us in this investigation.
“The victim was unable to indicate why this assault might have happened. It may be that a second articulated lorry, not further described, stopped at the scene of this attack at the time and we would like to speak to the driver of that lorry.”
