A man has died three weeks after being involved in collision with an ambulance on an emergency call in Lincolnshire.
The crash took place on the A607, at Waddington with the junction of Vanwall Road, on Wednesday January 25.
Three vehicles were involved, an ambulance which was entering Waddington travelling towards Navenby, a silver Vauxhall Vectra saloon and a black Toyota Prius.
The Ambulance was displaying emergency blue lights travelling to a patient call. There were no patients on board at the time.
Four people including the two crew from the ambulance were taken to Lincoln County Hospital. A passenger from one of the other vehicles has been taken to the Queens Medical Centre with serious injuries.
The driver of the silver Vauxhall Vectra was not initially admitted to hospital following the collision. However he was subsequently admitted this week on Monday February 13 and now has tragically died.
A post mortem examination will take place to try and ascertain whether the death is linked to the collision.
Police still wish to trace the driver of a dark coloured vehicle which was behind the silver Vectra in a line of traffic at the time of the collision on Grantham Road, Waddington.
Inspector Simon Heads, from the Serious Collision Investigation Unit, said: “I appeal for any witnesses to this collision who have not already spoken to the police to contact me. In particular, I would like the driver of the car following the silver Vauxhall Vectra to call me, as a witness, to help add to the information in our enquiry”.
Witnesses are asked to contact Inspector Simon Heads by calling 101, quoting incident 160, 25 January 2016.
