A father and son who were shot by a gunman in a north London shop were not the intended targets, a court heard.
Ahmet Paytak, 50, died and his 21-year-old son Huseyin was injured when four shots were fired into Euro Wines and Food store in Holloway in March 2009.
Another father and son duo working at the Hornsey Road shop were the real targets of a revenge attack in a feud between two gangs, the jury heard.
Ricardo Dwyer, 27, of no fixed address, denies murder and attempted murder.
Mr Paytak and his son were closing up the corner shop when two men pulled up on a motorcycle and the pillion passenger opened fire, hitting the 50-year-old in the stomach, the Old Bailey heard.
Huseyin's thigh bone was fractured by a bullet.
Prosecutor Edward Brown, QC, said: "There was another father and son pair who worked in the shop.
"They were the intended targets, not Mr Paytak and his son who were caught up quite by chance in what was by then a dreadful and deadly feud."
Mr Brown said the feud involving two Turkish gangs - the Hackney Turks and the Tottenham Turks - began two months ago when the alleged boss of the Hackney gang, Kemal Armagan, was injured and humiliated in a fight in a club.
"He had been publicly humiliated, pretty badly injured and was very angry. He was heard to shout out that he was going to kill those who had attacked him."
Mr Armagan, who is wanted for the shooting, blamed his rivals and in particular Mehmet Senpalit, whose father Pasa owned the shop where the victims worked, the jury heard.
Mr Brown added: "The evidence is plain that this was nothing less than a killing to order - a 'hit'."
The motorcycle rider Michael James, then 31, has been convicted of murder and jailed for life, the jury has heard.
