Businessman Harry Broadhurst was stabbed to death outside a Chelmsley Wood social club during a violent disturbance sparked by a bitter family dispute, a jury has heard.
Harry Broadhurst, 22, who was a stranger to those involved in the violence, was knifed in the abdomen after two other victims were injured with a machete and a hammer, Birmingham Crown Court heard.
Liam Cole, 29, Paul McAteer, 32, and Scott Smith, 40, all deny the murder of Mr Broadhurst, who was attending a charity boxing night at St Anne's Catholic Centre in Chelmsley Wood.
Opening the Crown's case against the defendants, James Curtis QC alleged that McAteer and Smith were "recruited" by Cole to join an attack on his father, Eamon Crawford.
Mr Curtis told jurors that Mr Crawford left Cole's mother when he was six and then refused to acknowledge him as his son, particularly with a view to paying child support.
During his opening speech, Mr Curtis alleged that Cole became enraged after hearing his father wanted to end formal court proceedings involving the Child Support Agency by offering him a "cheap bung" of cash. Cole, the Crown claims, regarded the offer as the "ultimate insult" and enlisted the help of McAteer and Smith to get his revenge.
On the day of Mr Broadhurst's death, Mr Curtis alleged, Cole phoned his father and told him he was "coming to sort him out". Mr Crawford, then aged 46, suffered wounds to the abdomen, head and hand during the violence on November 20 last year.
Another customer at the social club received a hammer blow to the head, while Mr Broadhurst, who was at the front of a pursuing group as the attackers fled, died after his vital organs were severed, the court heard.
Smith, of no fixed address; McAteer, of Crossfield Road, Kitts Green, Birmingham; and Cole, of Nearmore Road, Shard End, Birmingham, further deny conspiracy to cause grievous bodily harm to Mr Crawford. The defendants have also pleaded not guilty to wounding Mr Crawford with intent and assaulting the third alleged victim.
The trial, which is expected to last up to four weeks, was adjourned until Wednesday.
