A driver who suffered extensive injuries in a collision that left another motorist dead has put up a £10,000 reward to identify the person responsible.
Andrew Scottow was driving along the A47 near Dereham on Valentine's Day last year when he was forced to swerve to avoid a recklessly-driven black car, which has only been identified as a Peugeot.
The manoeuvre placed his Skoda Felicia in the path of a Peugeot 406, in which Kim Utting, who died in the head-on collision, was a passenger.
Mr Scottow was taken to Addenbrookes hospital in Cambridge with a brain hemorrhage, broken bones and a ruptured diaphragm. He remained in a critical condition for a number of weeks.
A police spokesman told the BBC: "Despite numerous appeals, the identity of the driver of the black car is still unknown, so Mr Scottow is offering a £10,000 reward for information leading to an arrest and conviction in connection with the collision."
Mr Scottow said: "Someone has killed someone, and they wake up every day knowing they have got away with it, and they don't care.
"I know someone knows, and I want to prick their conscience."
