Plea to drivers over Colchester sex assault
Police investigating a sexual assault on a woman in Essex have urged pedestrians and drivers to come forward with information.
Officers said people who were in the "busy" Shrub End Road, in Colchester, may have important information.
The 20-year-old woman was assaulted in an alleyway between the street and Egerton Green Road on Friday evening.
Essex Police said she had been unable to provide a good description of her attacker, who was wearing a hooded top.
Anyone who was in the area between 23:40 BST and midnight has been asked to speak to the force.
Officers have made house-to-house inquiries and are reviewing CCTV and making forensic examinations while patrols in the area have been increased.
