Police in East Lothian are investigating following a disturbance involving a number of individuals and their vehicles on the A199.
The incident happened around 1.35pm on Monday 26th November at Strawberry Corner, near to the A1 flyover.
Members of the public contacted the police reporting an disturbance between the males and that a firearm was discharged during the incident.
Officers responded and closed the slip-road of the A1 while they conducted a thorough search of the area and two of the vehicles involved were seized. The road remains closed at this time.
Further inquiries resulted in the search of an area in Cockburnspath, within the Scottish Borders, on Tuesday 27th November. Police are still in attendance at this location.
The investigation into the full circumstances surrounding this matter are continuing and anyone with information is asked to come forward.
Superintendent Angus MacInnes from Lothians and Sottish Borders Division said: “While we are still working to establish the exact nature of the incident on Monday, we believe this to be an isolated matter involving a group of people all known to one another. We do not believe there to be a risk to the general public.
“Local officers in East Lothian and the Scottish Borders are being supported by CID and specialist resources during the course of this investigation and if you believe you have any relevant information that can assist these inquiries then please come forward.
“In particular, we would like to speak to motorists who were on the A199 on Monday afternoon and may have dash-cam footage of what happened.
“I want to stress that incidents of this nature are incredibly rare and we have a dedicated team carrying out an extensive investigation to bring those responsible to justice.”
