Police are seeking witnesses to come forward after a 19-year-old was knocked unconscious outside a restaurant in Nailsea.

The assault took place outside Kebab Kitchen inside the Crown Glass Shopping Centre on September 5 at 12.10am.

The 19-year-old man was eating when he was approached by a man described as white in his late 40s to early 50s, who was bald and wearing a pink or red shirt.

The offender punched the 19-year-old to the right cheek, which police say was an unprovoked attack, knocking him briefly unconscious and left him with facial injuries.
