Wiltshire police is appealing for further information after a 19-year-old female was assaulted in Warminster last month (September).
They've released CCTV images of a man they hope can help with their 'extensive enquires'.
Officers have been investigating the assault since the night of the attack last month.
The woman, from the Warminster area, was walking along Weymouth Street at around 9.30pm when she was approached from behind and assaulted.
Detective Constable Matthew Parfitt, of Wiltshire Police, said he was keen to speak with the person in the CCTV images and appealed for potential witnesses with dash cam footage to come forward.
