A 21-year-old woman has been sexually assaulted in Portsmouth.
The woman was followed by a man while walking close to the Festing Pub, near Albert Road, in the Southsea area of the city, in the early hours of Sunday.
Police say she was then attacked and her screams may have been heard by nearby residents.
The attacker is described by police as being of Indian or Pakistani origin, of slim build, in his mid to late 20s, with wide set eyes and curly dark hair.
He was wearing a black or brown PVC waist length jacket and spoke English with a soft accent.
Police are also appealing to anyone who was in the area of a burger van opposite the entrance to Festing Mews - an area of garages opposite the Festing Pub.
Det Con Jo Morris said: "At this time in the morning there would have been someone in the area on a Saturday night out who may have heard something, may remember seeing the woman, or more importantly the man fitting the description of our suspect."
She also appealed for a man who offered to call the victim a taxi to come forward as a potential witness.
He was described as black and as having a Samsung mobile phone.
"I am keen to trace this male who may have seen her attacker," Ms Morris added.
