The assault took place in Peppermint, Wind Street, in November 2022.
South Wales Police say the victim sustained serious facial injuries after being attacked with a glass. Officers subsequently attended the scene and the suspect Emily Williams was identified and arrested.
Detective Inspector Chris Evans from South Wales Police said: “Violence will not be tolerated within the night-time economy and South Wales Police are committed in pursuing any offending.
“It is important that the public feel safe within the city centre at night, and we work in partnership with the Local Authority in providing Help Points and conducting pro-active operations within the area.”
