ABOUT 15 thugs were involved in the brawl in Ealing Broadway which left one man dead and another stabbed in the back.
Witnesses said the fight broke out in Northcote Road before spilling out into The Mall, in front of Costcutter on Tuesday. The group then moved across the street to Hamilton Road where one of their cars was parked.
A neighbour who asked not to be named, saw the fight at about 3.15pm on Tuesday.
She said: "It was a multi-cultural group. There was a bit of a punch-up but at first it didn't look like anything serious had happened. It looked like one of the guys was upset. Almost as if he was saying 'why did you do that?'. Then it looked like someone fled the scene and ran towards Ealing Broadway. One was helped into a navy blue car but he seemed OK. He was able to take his T-shirt off before getting in and it wasn't as if he had fallen to the ground.
"It didn't look like anything really serious until I saw the one who had helped him into the car walk around to the passenger side and I could see a blood stain on his back. He quickly got into the car and they drove off."
An estate agent working at nearby Rolfe East saw a man running away. He was described as black, about 6ft 3ins, with a bright pink top."
A 22-year-old man was pronounced dead at hospital. His friends had stopped in front of an ambulance in Gunnersbury Lane, Acton to try to get him help but paramedics were unable to revive him.
A post-mortem took place at Uxbridge Mortuary on Wednesday 7 August.
An 18-year-old has been treated and discharged from hospital.
Police said there was no sign of trouble by the time they arrived. They have launched a murder investigation and are appealing for witnesses. There have been no arrests.
Borough commander Nev Nolan, said: "This is a shocking and tragic event which has occurred in what is normally a very peaceful and safe area of the borough. At this stage, there is nothing to suggest that this incident is gang-related. Additional patrols have been put in place to provide further reassurance to Ealing's communities."
Detective Chief Inspector Howard Groves, of the Homicide and Serious Crime Command, added: "It would have been fairly busy in The Mall and in the Hamilton Road area at that time of the afternoon and people may have captured the incident on mobile phones or hand-held devices. I urge anyone who may have photographs or video footage to contact police as this may help us with our inquiries."
Anyone with information should call police on 101 or Crimestoppers anonymously on 0800 555 111.
