Hassan Isman Omer, a 31-year-old from Poplar in east London, has been named as the victim of a shooting in a nightclub on Boxing Day.
He died in hospital after suffering multiple gunshot wounds at around 3am on Thursday during a private function in the Avalon club on Shaftesbury Avenue.
Next of kin have been informed and a post-mortem examination is expected to take place this afternoon at Westminster Mortuary.
Two men - a 31-year-old and a 34-year-old - arrested on suspicion of murder have been bailed to a date in mid-February, Scotland Yard said.
The Avalon Soho describes itself as a cocktail lounge with live DJs every night.
Its website says it is "a revitalised venue that oozes creativity and class" which brings "a unique and stylish vibe to the heart of the West End's party scene".
A DJ who was at the event tweeted: "RIP to the person who lost his life last nite in front of me. I don't know who you are but I wish god has taken you into his hands.
"A stray bullet could have hit anyone and taken them also! I can't imagine his family right now."
A Metropolitan spokesman said: "Police and London Ambulance Service attended to find a man suffering from multiple gunshot wounds.
"He was taken by London Ambulance Service to hospital, where he died from his injuries.
"Detectives are continuing to appeal to anyone who was inside the Avalon nightclub at the event, or who witnessed events inside the club, to contact them."
