A motorcyclist remains in hospital with serious injuries this week, after what police believe was a targeted attack involving a group of bikers and several vehicles on the M74 in Scotland.

The incident happened at around 1pm on Sunday, August 2, between junctions 10 and 11 near Lesmahagow, when emergency services were called to reports of a disturbance involving a group of motorcyclists and people travelling in four vehicles.

A 63-year-old rider suffered serious injuries during the incident and was taken to hospital, where he remains receiving treatment.

Police Scotland says the attack appears to have been targeted and is continuing enquiries to establish exactly what happened and identify those responsible.

Detective Sergeant Craig Wait said: 

“We believe this was a targeted attack on the group of motorcyclists and it’s vital we trace the people responsible.

“One man has been seriously injured as a result of the attack and many others, including members of the public who witnessed what happened, have been left shaken.

“I’m appealing to anyone with information to come forward. Were you on the M74 near Lesmahagow yesterday and saw what happened? Did you see the motorcyclists or vehicles before the incident or the red Mazda and other vehicles leaving the scene? Do you have dash-cam footage which has captured anything of significance? If you do, please get in touch.”

A red Mazda, believed to have been involved in the incident, was later recovered in Ayrshire with its rear window smashed. Officers are still trying to trace the remaining vehicles involved.
