A woman in her 30s was attacked in Oxford after asking a group of four men to turn the music in their car down.
The woman was walking by Oxford Retail Park on Ambassador Avenue on Friday 18 March and asked the men to turn down the music in their car at around 9pm.
The four men then attacked her, causing an injury to her eye and a chipped tooth.
She was taken to hospital for further treatment and was later discharged.
Thames Valley Police have released images of three men who they believe may have “vital information” about the assault.
Investigating officer PC Czachur said: “We would like to appeal to anybody who recognises the men in these images to please get in touch as we believe they may have information in connection with this incident”.
