This is a woman police believe assaulted another woman during a night out in the city last month.Advertisement
The CCTV image shows the blonde woman standing outside The Assembly bar.
A 42-year-old woman from Grimsargh was either punched or headbutted by the woman pictured at 3.10am on Friday 18 May.
PC Rob Costigan said: “This appears to be an unprovoked assault in which the victim sustained a cut to both the inside and the bridge of her nose which required medical treatment.
“I would appeal to anybody that witnessed it or with any information that could assist with our investigation to come forward.”
Anyone with any information should call Lancashire Police on 101.
