A man dropped two with knockout punches in an incident on a city centre street.
The short video, which has been widely shared on social media, appears to show four men approaching another man on Talbot Street. One of the group, who is dressed in a brightly coloured t-shirt, gets close to the man.
This man steps to the right and throws a punch with his right hand which knocks the other man to the ground. He hits him again which leaves the man in the brightly coloured t-shirt seemingly unconscious on the ground.
