We are appealing for witnesses and dash cam footage following a fatal collision on A16 between Algarkirk and Kirton roundabouts on Friday 28 January.
Our force control room received a report of a collision involving a white BMW 420 which was travelling towards Spalding and a silver Toyota Yaris which was heading towards Boston. This happened at around 9.47pm.
The front seat passenger of the Toyota, a 76-year-old woman, sadly died at the scene whilst the 72-year-old female driver was taken to hospital with serious injuries.
The driver of the BMW, a male aged 37, was arrested at the scene on suspicion of causing death by dangerous driving and failing to provide a roadside breath test. He suffered minor injuries, and remains in custody.
If you can assist with our investigation or have dash cam footage, please contact us in one of the following ways:
