A CCTV image has been released as detectives investigate a sexual assault at a city centre park.
A young woman was walking home along the east side of The Level in Brighton when she was approached and attacked by a man.
The assault happened between 3.30am and 5.30am on Saturday.
The 21-year-old victim is now being supported by specially trained officers.
Sussex Police are now trying to track down a suspect in their investigation into the incident, and have released a CCTV image of a man they want to speak to in connection with the attack.
He has been described as 5ft 6in tall, slim, with brown eyes and dark, Afro hair styled in a number of thick top knots.
Detective Inspector Lee Horner said: “We need to trace the man in the CCTV image in connection with the incident and are appealing for anyone who recognises him to come forward.
“We would also like to hear from any witnesses or from anyone who has CCTV or dash cam footage which captured the incident.”
Anyone who can help Sussex Police with their investigation is being urged to report any relevant information online or call 101 quoting Operation Southfield.
