Andrew Scottow is so tormented by the fatal crash which left him in intensive care that he has tripled his reward to £30,000 to catch the erratic driver who caused the smash.

On Valentine's Day last year Mr Scottow, 26, swerved to avoid an rogue black Peugeot 307 snaking its away along the A47 towards Norwich.

Mr Scottow, living in Toftwood at the time, was forced to lose control of his red Skoda Felicia between Draytonhall Lane and the A1075 at Dereham, careering into a green Peugeot 406 travelling in the opposite direction, killing a mother of three.

Twenty months on and despite numerous appeals to catch the driver – they have never been caught.

Now Mr Scottow, a cafe manger in Sprowston, has said his determination to catch the driver, who police believe was a man, is stronger than ever and he has offered £30,000 for information leading to an arrest and conviction of the driver.

'I want to up my reward from £10,000 to £30,000 because it makes me angry to think someone is still out there thinking they got away with it,' he said.

'It shouldn't cost anything. And I know the best way to get over the crash is to live my life without worrying, and that is what I am trying to do.

'But at the same time I just want to get back at that person for making my life so different to how it was before.'

Kim Utting, 52, was travelling from her home in Litcham to Dereham with her daughter for a morning of shopping when the black car caused the fatal crash. She died at the scene.

Mr Scottow's post-traumatic amnesia since the crash means he does not remember the accident – but now he has to write everything down to remember what he is doing.

'I am doing as much as I can to live my life. But the driver knows I know they are out there, and they are just living their life,' he said.

Using his life savings, Mr Scottow wants to encourage anyone who knows the driver of the black car to come forward.

Police received a number of calls following the initial £10,000 reward offer in June which led to one man being interviewed under caution.

A vehicle was examined and the investigation continues.

Chief Inspector Chris Spinks, head of the joint Norfolk and Suffolk Roads Policing Unit, said: 'We continue to follow every line of enquiry open to us in order to solve this case and find the driver responsible.

'Clearly this is a large sum of money the victim is offering as a reward which ultimately shows the impact serious and fatal collisions can have on victims.

'We obviously support any action which could lead to us receiving further information about the collision which could lead to a successful prosecution and bring closure for all those involved.'
