Scott Clark, of Loves Farm, St Neots, was killed in a crash with a tractor on Offord Road, between the Offords and Godmanchester, at 1.55pm on June 13. The 23-year-old was driving a blue Vauxhall Corsa. The driver of the tractor, a 58-year-old man, was not injured. Officers want to trace a cyclist and two women who might have vital information in connection with the crash. PC Theron Pearman said: Im keen to trace this cyclist as several other witnesses remember seeing him at the scene but leaving before we could speak to him. I would stress he is not in any way at fault for the collision but is likely to have seen what happened. I would also appeal to two women who were at the scene to get in touch as we have not been able to make contact with them since the incident. INFORMATION: If you were the cyclist who witnessed the collision, or know who he is, call PC Pearman at the Roads Policing Unit on 101.
