Police are following 'several lines of enquiry' generated from the offer of a £10,000 reward to catch and convict the mystery driver who caused a fatal crash on the A47.

Andrew Scottow, from Middlemarch Road in Dereham, was injured in the crash on February 14 last year when a snaking car forced him to lose control of his red Skoda Felicia between Draytonhall Lane and the A1075, heading towards King's Lynn.

It smashed head-on into a green Peugeot 406 travelling in the opposite direction, killing mother-of-three Kim Utting, 52, who was on her way for a shopping trip with her daughter Emma Herring.

The black Peugeot drove off and – 16 months after numerous police appeals and trawling through CCTV – he has still not been caught.

Last month, Mr Scottow, 26, offered £10,000 from his life savings as a reward for information leading to an arrest and conviction of the rogue driver.

And the bold move has given police new avenues of inquiry to follow.

Chief Inspector Chris Spinks, head of the joint Norfolk and Suffolk Roads Policing Unit, said: 'Our recent appeal resulted in a number of calls to the officer in the case which has enabled her to follow several lines of enquiry.

'Although the collision happened over a year ago the appeal has triggered some information being given. However, we would still urge more people to come forward with information, no matter how insignificant it may seem to them.'

'The reward is a considerable amount of money and goes to show the impact serious and fatal collisions can have on victims. Finding the driver of this vehicle will allow us to progress our enquiry and ultimately help bring closure to Andrew and Mrs Utting's family.'

Anyone who witnessed the collision or the manner of driving of any of the vehicles involved should contact the Serious Collision Investigation Team on 101.
