POLICE have spent the weekend taking another look at the scene of a collision on the A47 between Guyhirn and Wisbech in the hope of tracing potential witnesses.
Police have renewed their appeal for witnesses three weeks after the incident on Saturday November 12.
On that date, the road was closed for almost 12 hours while forensic officers scoured the scene.
Investigations are continuing to establish the circumstances of the incident but police have confirmed a firearm was involved.
In the incident a silver Audi A4 left the road shortly before 4am and flipped onto its roof. Two people were travelling in the vehicle and suffered minor injuries.
They both received hospital treatment but were released the same day.
Detective Inspector Jon McAdam said: “Investigations continue to establish the circumstances of this collision and we are still treating it as an isolated incident.
“Officers have spent the weekend doing anniversary checks in the area of the collision as we still believe there are witnesses who we have not yet spoken to.
Det Insp McAdam is urging witnesses to come forward.
“I would urge anyone who saw the collision or anything suspicious on the road in the moments leading up to the collision to contact me,” he said.
Anyone with information should contact Det Insp McAdam on 101 or Crimestoppers, anonymously, on 0800 555 111.
• A 40-year-old man was arrested in connection with the incident and is currently on bail until December 21.
