Derbyshire Police want to speak to a woman after two women were assaulted in Chesterfield.
At around 2.10am on Sunday, July 21, a 23-year-old woman was assaulted on the dance floor of Association, in Corporation Street.
The women involved then went outside the club, where another woman, also aged 23, was hit in the face and suffered bruising.
Since the incident happened, police have identified a woman they wanted to speak to and she has been eliminated from the inquiry, which is why they are now turning to the public for help.
