The man, from Essex, was arrested in Chelmsford late last night (January 3) on suspicion of death by dangerous driving and ABH. He has since been taken to Chelmsford Police Station and is expected to be transferred to Cambridge later today. Police were called to the B1091 in Yaxley at about 11.15am yesterday morning to reports of a collision between two pedestrians believed to be in their late teens or early twenties - and a BMW. An air ambulance attended, with a police helicopter and dog unit searching for the driver who fled the scene on foot. A police spokesman added that officers are also looking at whether a call from a member of the public reporting a man entering their home is connected to the incident, as well as the discovery of a briefcase containing a quantity of cash which was recovered in the area.
