Police have admitted to mowing-down and killing a dog that was running loose on a Welsh motorway.
Officers from North Wales Police force said the canine was chased up the A55 at from Llanfairfechan roundabout to the Conwy tunnel.
The incident – which had “potential for a serious collision” happened during the early hours of Monday.
An officer who had tried to take hold of the dog was bitten.
Chief Inspector Darren Wareing said that the North Wales Police control room received several calls shortly after 3am and the decision to take action was not taken “lightly”.
He said: “The only safe option was to run the dog over at sufficient speed to ensure that it was destroyed and would not suffer. Other methods of destruction were considered, but were ruled out on the grounds of public safety.”
Wareing said that several attempts were made to catch the dog.
“One car and an HGV had to swerve to avoid the dog whilst the officers remained on foot in the carriageway,” PA reported him commenting.
“The potential for a serious collision was present throughout, and in the circumstances there was no alternative way that officers could contain the dog and minimise risks to motorists.”
He added: “Fast roads such as the A55 present inherent risks, and to have vehicles including an HGV having to swerve in the dark was deemed unacceptable as the officers witnessed a number of near misses, and were highly concerned about the potential aftermath of a high-speed collision.
“Both officers have their own dogs and did not take this decision lightly. Due to the seriousness of the incident it needed bringing to a conclusion quickly for the safety of all concerned.”
