Teenagers openly carry knives on the Isleworth estate where a man was stabbed to death , according to one resident.
A 28-year-old man, named locally as Sahil Roy, was stabbed to death on the Ivybridge estate, in Summerwood Road, Isleworth , on Sunday (April 10) afternoon.
Police have arrested a 22-year-old man, who remained in custody on Monday (April 11), on suspicion of murder.
People living on the estate have spoken of their shock following the killing, as well as calling for action over knives and drug crime.
Last week, a former detective said it was possible to buy knives similar to those used in the film Rambo on the streets of Hounslow.
'I had cross words with a bloke and he pulled a knife on me'
One man, who asked not to be named, told getwestlondon : "There are kids on this estate openly carrying knives. People have reported it but the police don't seem to do anything about it.
"I had cross words with a bloke a couple of months ago and he pulled a knife on me.
"You see people dealing drugs here and most of those doing it aren't more than 15 or 16. Most of them don't even live on the estate. It's a shame because it's a nice place to live."
Another man, who also asked to remain anonymous, said: "A week ago there was a stabbing on the alleyway towards Asda and now this.
"I've got children and it's a bit scary even to let them outside but you can't keep them indoors all the time."
There were flowers near the scene of the stabbing, which remained cordoned off on Monday afternoon as forensics officers searched the scene.
A woman who also declined to give her name said: "This has come very much as a shock.
"There have been a lot of problems on the estate with people selling drugs and there are a few little gangs that hang around the estate, but you don't expect anything like this."
Police have asked anyone with information to call officers on 101 or Crimestoppers, free and anonymously, on 0800 555111.
