All three of the men arrested in connection with the murder of Luke Fitzpatrick on Saturday have been bailed pending further inquires.
Two 17-year-olds and a 31-year-old were arrested on Saturday night and taken to separate London police stations.
The 31-year-old has been bailed to return in late June pending further inquiries.
The two 17-year-olds have also been bailed and are due to return to the police stations later this month.
Police and paramedics were called to Coles Green Road at 11.30pm on Saturday following reports of a stabbing.
Mr Fitzpatrick, 25, who is reported to have been a roofer, died of stab wounds at the scene.
A 56-year-old, who is thought to be Luke’s father, named locally as Bernard Fitzpatrick, was also injured as he tried to protect his son.
He is in a serious but stable condition in hospital reportedly suffering a punctured liver.
Both victims had been at the Ox and Gate pub in Coles Green Road where people had gathered to watch the Champions League final.
It is believed that a fight broke out which then spilled outside the pub before the victims were stabbed in Crest Road.
According to neighbours the victim’s mother was on holiday with her other son at the time of the attack and flew home yesterday.
