A man is in custody in connection with a fatal collision in Guildford at the weekend.
Surrey Police discovered a man with serious head injuries in Portsmouth Road near the junction with Turnham Close at around 3am on Saturday. He was pronounced dead at the scene.
Officers would still like to trace the drivers of two other cars - a large silver saloon, possibly an old style Mercedes and a small red hatchback which was driving behind it. Both cars were seen travelling through Guildford's gyratory system at around 2.55am on Saturday, 20 August and may have witnessed the incident.
Both drivers are being urged to contact Surrey Police as a matter of urgency quoting reference P16188470. Information can also be passed anonymously to the independent charity Crimestoppers on 0800 555 111.
