We are appealing for a key witness to come forward as part of a Southampton assault investigation.
It was reported to police that between 2.50am and 2.55am on Sunday 12 May, two men were involved in an altercation outside Leisure World, during which one of the men was knocked unconscious.
This man suffered serious but not life-threatening head injuries and was taken to hospital for treatment.
Officers would like to talk to a woman who spoke to both men and also helped the victim after the assault, as she will have witnessed the incident.
A 21-year-old man from Southampton was arrested on suspicion of inflicting grievous bodily harm and has been bailed until 7 June.
If you witnessed this incident, or can help us identify someone who did, please call us on 101, quoting 44190162876.
