A man has been arrested after a 21-year-old woman was raped in Southwater last month, police said.
A spokesperson for Sussex Police said the incident happened in Mill Straight, just outside Southwater Country Park, on Tuesday January 13.
Between 10.30pm and 11pm, the woman was raped on the pavement next to a lay-by in the road, the spokesperson added.
Police said a 21-year-old Horsham man has been arrested on suspicion of rape, and is currently on police bail until March 5 while enquiries continue.
Officers are seeking a car owner who they believe may have information to help their investigation.
Police said the car, a 4x4, possibly a Jeep, silver in colour, and of an older style, between seven to ten years old, was seen parked in the road on the evening of the incident.
Detective constable Karrie Bohanna said; “There is no suggestion that the 4x4 owner had anything to do with the offence, but it could be that they saw something which may now help us, even without realising it at the time.
“If you can help in this or any other way, please contact us via firstname.lastname@example.org or call 101, in either case quoting serial 1298 of 15/2.
“You can also contact the independent charity Crimestoppers anonymously on 0800 555 111.”
