Police are appealing for witnesses following a serious injury road traffic collision in Milton Keynes.

The appeal follows an incident that happened between 11.25pm and 11.38pm on Thursday (7/11) on the M1 southbound between junctions 14 and 13.

A collision happened between a red HGV and a black Audi A6 on the M1 southbound carriageway between junctions 14 and 13. Following that collision, a second collision then happened between the Audi A6 and a white Mercedes A-Class.

The M1 southbound was closed for two hours while emergency services attended the scene.

Three occupants of the Audi A6 were taken to the John Radcliffe Hospital in Oxford. One woman in her nineties sustained serious injuries and remains there currently in a stable condition, and the two others sustained minor injuries and were discharged.

The Mercedes A-Class driver was treated for minor injuries at the roadside and the HGV driver was not injured.

Investigating officer Sergeant Daniel Collett said, “I am appealing for witnesses to this road traffic collision, during which a woman in her nineties sustained serious injuries and two others also had to attend hospital.

“I would like to appeal to other motorists on the M1 at this time who may have seen or heard about this incident to get in touch with us to help with our investigation. I am asking also for anyone with dash-cam footage to please review it to see if there is any evidence of this collision on there, which could be of assistance.
