Two men have been charged after a crash on the M8 in Glasgow which left two police officers injured.

In July a crash involving a Mercedes A45, an unmarked Volvo S90 police car and a Mercedes CLS near junction 13 saw seven men taken to Queen Elizabeth Univerity Hospital and Glasgow Royal Infirmary.

Hospital staff described the condition of a 48-year-old police officer, 43-year-old man, and a 39-year old man as critical.

A 27-year-old man who left the scene was arrested in connection with alleged road traffic offences and later charged.

Police said two other men had been charged, a 27-year-old man who is due to appear at Glasgow Sheriff Court on Thursday, August 29 and a 33-year-old man.

A 48-year-old police officer and a 43-year-old man remain in a stable condition in hospital.

A 38-year-old police officer and a 31-year-old man were discharged following treatment.

Chief Superintendent Hilary Sloan, head of road policing for Police Scotland, said: "My thoughts remain with our colleagues and members of the public who were injured in this incident. Our officers are being supported as they continue to recover from their injuries.

“I’d also like to thank the public for their support and information provided throughout our investigation.”
