A man has been arrested and a pedestrian is fighting for his life following a collision between two vans on the M8.
Emergency services were called to the motorway following a crash at around 4pm on Monday between a grey Renault Trafic SL28 van, a Volkswagen Crafter van and a 26-year-old man near Harthill Services.
A medical helicopter took the pedestrian to Queen Elizabeth University Hospital in Glasgow for treatment.
His injuries are described as life-threatening.
Officers have confirmed that a 33-year-old man has been arrested in connection with the incident and released pending enquiries.
A section of the M8 westbound was closed for around five hours to allow a full collision investigation to take place and reopened at around 9.35pm.
Sergeant Scott Sutherland, of Motherwell’s Road Policing Unit, said: “Our enquiries to establish the full circumstances of the crash are ongoing and I would urge anyone who may be able to help to get in touch.
“We would be especially keen to hear from anyone who may have dash-cam footage of the incident.
“Anyone with information or footage can contact officers on 101, quoting incident number 2210 of October 17.
“I’d also like to thank the motorists who were affected by the road closure for their patience while we carried out our investigation.”
