Jersey Police have released CCTV footage which they hope will jog someone's memory of an alleged sexual assault on a 28-year-old Asian woman.
The assault is said to have happened sometime between 2.30am and 4.30am on Sunday December 18th 2011, in the grounds of Royal Bank Court on College Hill.
The woman had become separated from friends following a night out in town.
The suspect for the offence, who was seen in La Motte Street with the victim, is described as wearing a dark coloured beanie style hat, a light brown/camel-colour jacket, dark trousers and dark shoes.
The victim, who is described as around 5'2 with long dark hair and wearing a black and white spotted top, black trousers, black boots and carrying a large white handbag, had earlier been out with friends at the La Cala and Mimosa nightclubs and had been seen later walking alone along Bath Street towards Snow Hill.
Police are particularly keen to speak to two women, seen on CCTV with another man, who walked past the victim and suspect as they walked down La Motte Street at around 2.30am. On the evening in question it was raining heavily.
Police would also like to identify two males who may be able to assist them with their enquiries seen on CCTV in La Motte Street at 2.19am and at 3.45am.
A dedicated team of officers has been working on the case but despite a good response from the public have not been able to identify the attacker.
Detective Chief Inspector Alison Fossey, who is leading the inquiry, said: "So far the public have been a great help to the enquiry but we believe more people would have seen the victim that night and we would be keen to speak to them.
"From our viewpoint this is a serious attack on a young woman and we are keen to catch the man responsible. We also want to urge other young women to be vigilant on a night out. These assaults are rare, Jersey is a very safe place, but it doesn't hurt to be careful."
