Police are putting on additional patrols in Ipswich after a woman was raped in the early hours of Saturday morning (20th July) and say they have now spoken to more than 200 people as part of their investigation.
Detectives say they hope the extra patrols will provide reassurance to the public.
The 18-year old was attacked as she was walking along Silent Street at around 3am. She was grabbed from behind and dragged into a car park where she was raped.
The male suspect is described as black with curly hair.
Police say early indications are that the risk of a similar incident occurring in this area is low.
But are reminding people to avoid walking alone in the early hours of the morning and to always plan your journey home by walking in groups, or using a taxi.
""This was a terrifying attack on a young woman and she has been incredibly brave in coming forward and working with our officers in order to help us try to identify the offender. I am appealing for anyone who believes they either know of, or saw a man in this area, matching this brief description we have issued, or who was in the town centre area or nearby between 2am and 4pm, to contact us straight away."
Specialist trained officers are continuing to support the victim, as work to identify the offender continues.
House-to-house, forensic and CCTV enquiries are also taking place.
Detectives are appealing for anyone who may have seen the woman walking from the town centre towards Silent Street or have seen a male matching the description above to come forward, or anyone who was in the nearby area between 2am and 4am this morning.
Officers would also like to hear from anyone who drove along nearby roads between 2am and 4pm who may have dash cam footage, or anyone living near to any of the routes mentioned who has private CCTV.
