Police have named a man who died after being stabbed near a nightclub in east London as Trei Daley, 26, from Bromley.
At 4.30am on Saturday, two men entered an east London hospital suffering from stab wounds.
Mr Daley later died of his injuries while the second, a 24-year-old male, has been discharged.
Metropolitan Police said a post-mortem examination will take place for Mr Daley in due course and his family has been informed.
DCI Jim Eastwood said: “I want to express my most sincere sympathies to Trei’s family.
“They are being supported by specialist officers, and a dedicated team of detectives will be doing everything possible to bring to justice whoever was responsible for this tragic killing.
“Officers have already spoken with a number of people who were in the area, and I am grateful for their assistance.
“But there will be others who saw or heard something, and I need those people to come forward and speak with detectives.”
Officers have established that Mr Daley was stabbed near to the Colour Factory nightclub in Queen’s Yard, just off White Post Lane in Hackney Wick, at around 4.30am.
No arrests have been made.
An urgent investigation is under way, led by detectives from Specialist Crime and supported by colleagues from the Met’s Central East BCU.
Matt Kruzynski, who works at a bar near White Post Lane, said he was shocked by the incident as Hackney Wick has always felt very safe to him.
Speaking outside the police cordon on White Post Lane, he said: "Hackney Wick is my local drinking spot, I spend a lot of time here.
"I have always felt very safe here. Nothing like this has ever happened while I've worked in Hackney Wick. The area has a bad reputation because of how it used to be, but it has changed a lot.
"Even at one or two in the morning after finishing work, I've never felt worried about walking home by myself.
"This is a very family friendly area. It's normal to see people pushing prams or taking their dogs for a walk at midnight.
"I'd consider moving here for sure, the only reason I wouldn't is because the cost of rent here is so high."
He added: "This would usually have been one of the biggest business days for us with the match at West Ham. Epecially in January and February a closure like this is a big blow."
