A man who was killed in a knife attack in Edmonton, north London on Saturday has been named by police as Julio Gomes.
The 29-year-old was pronounced dead at the scene in Houndsfield Road shortly after 8pm last night.
The suspected attacker was arrested after being chased and detained by nearby revellers from a birthday party being held at the Old Edmontonians FC clubhouse.
The 40-year-old suspect was in hospital having been arrested. Police say they are not looking for anyone else in connection with their investigation.
Julio Gomes, 29, has been named as the man who did not survive a stabbing attack last night despite the efforts of nearby partygoers who found him and administered CPR
Detective Chief Inspector Paul Considine said: 'We continue to appeal for information following Julio's death and need anyone who was present at the Old Edmontonians FC clubhouse that evening to come forward.
'A crime scene remains in place and specialist forensics team are working on this case.
'The incident is not thought to be connected to the event or the football club but we know lots of people were out and about that evening. Anyone with information, no matter how insignificant they think it is, should contact police or Crimestoppers as soon as possible.'
Guests at the nearby 30th birthday party noticed when a fatally-injured Mr Gomes wandered onto the football pitch near the Old Edmontonians FC clubhouse, Edmonton in North London after being stabbed three times.
Heroic partygoers at the 30th birthday party function restrained a knifeman while others tried to keep the stab victim alive.
He was followed by a man carrying a knife who was held down by five or six guests until police arrived.

At this stage, police are not looking for anyone else in connection with this investigation.
The Old Edmontonians football club were holding a private function in their clubhouse at the time the unnamed victim collapsed outside, and was discovered by a guest who then called the police.
A spokesperson for the club told MailOnline: 'The stabbing didn't happen at the event, we think the man came running from across from the other side of the park and then collapsed near to the clubhouse.
'It was a private function for adults that including attractions like sumo-wrestling and gladiators.'
'We were busy running the event inside the clubhouse when a guest came in to say "I think someone's been stabbed" and called the police.
'In the circumstances it was a very somber mood. When people heard they just finished their food and then left. It happened quite early on.'
Detectives are keen to hear from anyone who attended the event and may have seen the incident.
John Gunn, who lives behind the football club, saw ten police cars flying down his residential street after the fatal stabbing.
The 51-year-old carpet fitter said: 'I was indoors watching TV with my wife when I heard a lot of sirens.
'I came out and saw about ten police cars flying down the street and there were officers everywhere.
'The ambulance stopped at the end of the street right by the entrance to the football club - it was shocking.'
'There is a hall there and they hire it out for parties and events once or twice per month.'
The death comes less than 24 hours after a 34-year-old man died in hospital on Saturday after suffering stab wounds during an incident at a chicken shop at Grove Park in Lewisham.

Mr Gomes was confirmed as the 109th person to be killed in the capital so far this year, fuelling concerns that 2019 will see a heavier death toll than 2018's 134 murders - which included 70 stab deaths and 24 young people killed.
