Avon and Somerset Police have released CCTV images of a potential witness they are trying to trace as part of their investigation into an assault in Midsomer Norton.
A 22-year-old woman was walking along Priory Close at just after 1am on Saturday (29/8), when she was attacked by a man, described as white, of average build with short dark hair.
He was wearing blue jeans and a light blue hooded top.
The man ran off after being disturbed by a resident.
The victim was taken to hospital but has since been released.
Officers are trying to identify the woman in the CCTV images who they believe may have spoken to the offender after the offence.
If you recognise yourself in the images, or know who the woman is, please call the police.
Officers are also asking anyone who was in the Priory Close area or in the area of the Esso Petrol Station in Church Lane on Saturday night, or the early hours of Sunday morning, to contact them if they saw or heard anything suspicious.
If you can help, call 101 and quote reference number 95135/15.
