Harrogate Police is asking anyone who attends the Revolucion de Cuba club in Harrogate to cast their minds back to December.
On the night of 10 December, a woman in her 20s was hit in the face, resulting in a large cut to her lip that required several stitches.
Police say they know this is a long time ago, however, the incident has only recently been reported to us due to the distress and anxiety that the victim felt following the incident.
To help our appeal, the victim has bravely shared a photograph of her injury.
The assault happened at around midnight as the victim went to retrieve her coat from behind a chair in the upstairs area of the club. Shortly after the attack, a group of woman spoke to the victim.
Investigating officer, PC Sylvia Matla said:
I am appealing to the group of women to come forward along with any witnesses who saw what happened or can help us identify the suspect.
This attack caused the victim apprehension and distress but more importantly, anxiety causing her fear of reporting this incident to the police for some time.
I would like to reassure anyone who is the victim of crime, that North Yorkshire Police will investigate all crimes regardless of the time passed since it happened.
If you have information that can help the investigation, please email Sylvia.Matla@northyorkshire.police.uk
