Joe Cordina is on trial charged with two counts of assault by beating after a fight on 27 February.
Cardiff Magistrates' Court hears that Joe Cordina was "set up" during a fight at a petrol station in February
Former boxing world champion Joe Cordina was "retaliating" during a fight where he punched a man at a petrol station, a court has heard.
Cordina is standing trial charged with assault by beating relating to an incident on 27 February involving Jamie O'Brien, who previously admitted a charge of assault by beating. A second assault by beating charge against Cordina was dropped on Tuesday.
Cardiff Magistrates' Court heard the altercation came to light days later, after a video was published on Wales Online, filmed by a witness at a Texaco garage in the Pentwyn area of Cardiff.
O'Brien's sister told police her brother "hated" Cordina, the court was told, and she feared he had "sought out" Cordina.
