Police have confirmed that a 35-year-old woman from Bedford died in a multi-vehicle collision on the M1 yesterday.
She was driving a black Volkswagen Golf and was declared dead at the scene.
Three other occupants of vehicles were taken to Milton Keynes Hospital for treatment to minor injuries.
Police were called to the scene on the northbound carriageway at 7.55am following the collision on the exit slip road of Junction 14. Four cars and a heavy goods vehicle were involved.
A 55-year-old man from Warwickshire was arrested yesterday on suspicion of causing death by dangerous driving. He has been bailed until September 5.
Sgt Simon Hills from the Joint Operations Unit for Roads Policing, said: “The collision happened at a very busy time of the morning so we would ask anyone who witnessed it to contact us. With five vehicles involved it was quite a large scene but we were able to keep one lane open.
Thames Valley Police are appealing for witnesses. A spokesman said: “We would like to thank the public for their patience while we worked with our emergency services partners to help those involved and carry out our investigation.
“However it was extremely disappointing to see some people taking photos and footage on their phones while we were trying to help those involved. I am not sure why anyone would think that kind of behaviour is in any way acceptable or respectful to those involved or their loved ones.”
If you have any information which can assist with the investigation please call the 24-hour Thames Valley Police enquiry centre on 101.
