A young woman was sexually assaulted on a beach after leaving a nightclub where she was spending a night out with friends.
The woman was at Sheiks nightclub, in Bognor Regis, West Sussex, when the suspect first assaulted her at around 3.30am on Sunday morning.
He then took her to the beach close to the seaside town’s pier where he carried out a second attack.
Police have not released the woman’s age and say she is being supported by a team of specially-trained officers.
Patrols have been stepped up in the area while the suspect is still at large, police said.
The man is described as white, with short blond hair, and around 5ft 7ins tall.
He was wearing a blue/green top, skinny jeans, and a pair of white socks, police added.
District Commander, Chief Inspector Jon Carter, said : “This is a serious offence, and I appreciate that it may cause some to be worried about their safety when out at night in Bognor.
“The investigation team will work tirelessly to identify the person involved in this matter and bring them to justice.
“Sussex Police are working with other partners to introduce new measures to keep the district safe.
“In addition, specific police patrol activity, and work with licensed venues is continuing to keep our area safe, especially during the late evening and night time.”
People with information are urged to call the police on 101, quoting Operation Wingrave.
