A 25-year-old woman from Worthing was raped after she walked with her attacker along Littlehampton Road in Worthing at around 1am on Sunday morning, October 27.
Police have now issued still and moving CCTV footage of a man and the victim.
Detective Inspector John Wallace said: “While we have issued footage in previous appeals I hope this new footage will prompt people to come forward. It shows the two people walking together in Broadwater Road close to the Broadwater public house at 12.40am.
“We are showing the victim because she wore distinctive clothing which people might remember, although the lighting in the CCTV footage has created a bleaching effect on the colours.
“The barefooted woman, dressed distinctively in a red leather jacket and shorts and carrying her shoes, met the man somewhere along the A24 Broadwater Road, possibly after Northbrook College.
“They walked together from the direction of the town centre into South Farm Road then West into Poulters Lane and along Littlehampton Road. They would have been seen walking together for more than 1km before he attacked her.
“I am hoping that the CCTV and photographs of the man may jog someone’s memory that night or indeed they might recognise the man. She was talking with the man who walked alongside her before he raped her in an alleyway next to the Mr Clean Carwash on Littlehampton Road.”
The suspect is described as white, in his early 20s, around 5 ft 3 in, with short dark hair and wearing dark clothing.
He spoke with an accent and English may not be his first language.
DI Wallace added: “We would like to hear from anyone who saw the two people in Broadwater Road and later in the Littlehampton Road that Sunday morning.
“Did you see the woman or the man alone or together?
“They met somewhere along Broadwater Road and would have been seen walking together for some minutes.
“If you saw them or recognise the man and know his whereabouts please call 101 or email email@example.com quoting Operation Equator. You can also call independent charity Crimestoppers anonymously on 0800 555 111.”
