Detectives in Preston have released CCTV images of a man they want to speak to after a sexual assault in the city.
Between 2.50am and 3.10am on Monday (September 26), a 22-year-old woman was walking home after a night out.
As she continued on Adelphi Street and Plungington Road, the victim was talking on her mobile phone when a man approached her from behind.
The offender put his arm around her waist before the female shrugged him off and stopped to allow him to pass.
While outside the Wellfield Pub, the same man returned before sexually assaulting her. He was disturbed by a taxi driver before making off from the area.
The woman returned home before reporting the offence to police.
The suspect is described as Asian, in his mid-30s, of chubby build wearing a black top and trousers.
