The man shot dead outside a birthday party in Harlesden has been named.
Shawn Callum, 26, from Paddington died from a single gunshot wound after leaving the party at Stonebridge School on Sunday.
Police have released a copy of the ticket issued for the event, called 'I Feel Good', to urge witnesses to come forward.
There were around 150 to 200 people at the party and police are urging them to get in contact.
Officers were called at around 2.30am to reports of a shooting in Shakespeare Avenue.
Mr Callum was taken to Central Middlesex Hospital by London Ambulance but later died.
A post-mortem revealed the cause of death was a single gunshot wound.
A neighbour, who lives just yards from the murder scene on the Stonebridge Estate, called for tougher sentencing for those carrying guns.
The 48-year-old father-of-three, whose cousin was shot dead on the same estate a couple of years ago, said: "Things have improved and we can't let this isolated incident bring the community down again. It does make you feel worried about your own children but you can't wrap them up in cotton wool.
"I remember when it was bad years ago and we can't let it go back to that. The law on gun crime is far too lenient. People carrying guns just get a slap on the wrist and this is not working.
"These guys are career gangsters. They should get 10 years for possession. I've seen it from the beginning and youngsters need people to talk to people who have experienced this before. People who can pass down their knowledge.
"Parents are to blame. Everything starts at home. And what is worse is to think it is my generation who are the parents to these kids.
"I lost my cousin a couple of years back to gun crime and he was in his early twenties. I have also lost friends. Gun crime has affected this whole community and it is totally unacceptable."
An incident room has opened under DCI Fiona Mallon of Operation Trident, which investigates black on black gun crime in the capital.
Anyone with information should call the incident room on 020 8733 4704 or Crimestoppers anonymously on 0800 555 111.
