Police investigating an assault in a Roath fast food restaurant last month have released an image of a man they want to identify.
A 29-year-old man was punched while in Miss Millies on City Road at around midnight on Saturday November 24.
The suspect, who appeared to be arguing with a female customer in the shop before the assault, drove off in a grey car which could have been a Volkswagen Golf.
Officers are also appealing to the woman seen arguing with the suspect to contact them.
PC Daniel Wood: “This was unprovoked assault which could have resulted in much worse injuries.”
Anyone with information is asked to contact PC Wood on 07584 004 460 or Crimestoppers anonymously on 0800 555 111.
