Police are asking people to come forward it they know anything about a serious sexual assault in Oxford on Saturday night.
Police were called at about 7.50pm, to reports a 17-year-old girl had been seriously sexually assaulted as she walked along Sandy Lane West.
As she passed Bampton Close, she was grabbed by a man who attempted to rape her, before she managed to escape and run for help.
A full account has now been taken from the victim and the matter is being treated as an attempted rape.
The man is described as black, in his late 20s to early 20s, skinny, around 6ft, clean shaven, and spoke with a deep voice.
He was wearing a black and grey striped beanie-style woollen hat, a black shiny or silky hip-length padded jacket, dark blue or black wide leg jeans with a distinctive white or light coloured line pattern on right bottom pocket, and black trainers, possibly Nike Air style with hole in heel and a florescent green band round back of heel.
Detective Sergeant John Linsdell, investigating officer, said:
"The assault happened on a public footpath in the early evening, so I am hopeful someone may have seen a man matching the above description hanging around the area.
“Fortunately the victim was not injured in the incident, but has obviously been left very shaken and distressed.
“A team of detectives are working to catch the person responsible and I would urge anyone with any information which may help with the investigation to contact me.”
